Question 47

How to customise candlestick colors

Accepted Answer

Candle Colour & Chart Appearance
Every trader reads charts differently.
Some rely heavily on candle momentum. Some look for rejection. Some prefer to focus on trend continuation over short-term pullbacks.
Yet most trading platforms present charts in the same default color scheme, green for bullish and red for bearish, with the same background, grid intensity, and visual contrast.
Over time, this forces you to adapt to the chart.
Instead of letting the chart adapt to how you trade.
How to Personalise Chart Colors
Chart Appearance Customisation on Sahi allows you to personalise how price movement is displayed, helping align the chart with your own visual interpretation of the market.
On Mobile
Open any chart and just click on the three-line menu at the top right corner ---> 'Setting' --> and go to 'Colors.'

From here, you can customise candle body colors for positive and negative moves, along with background, grid lines, crosshair, session breaks, and text.
On Web
Open a chart and access the Chart Settings panel.
Navigate to the Colors tab and modify the required chart elements.
Your personalised settings will reflect immediately once you click on 'save'.
Some may want stronger contrast between bullish and bearish candles to clearly identify trend continuation. Others may prefer a softer color distinction to reduce visual noise during consolidation.
You can customise how positive and negative candle bodies appear on your chart, as well as their wicks, allowing price movement to stand out in a way that matches how you process setups.
This becomes particularly useful when monitoring short timeframes where momentum shifts can occur rapidly.
Apart from candle colors, you can also personalise:

chart background

grid lines

crosshair

session break markers

text colour

Adjusting these elements can improve readability, especially when analysing multiple charts during live sessions.
Some traders prefer a darker background with reduced grid contrast for trend clarity, while others may want stronger grid visibility when working with support and resistance levels.
Improve Recognition During Live Markets
When charts are visually aligned with your trading style, it becomes easier to:

recognise breakout continuation

identify potential reversals

distinguish trend from pullback

track momentum shifts

Instead of relying only on indicators, personalised chart visuals allow price action itself to become more readable.
Also, if you want to revert back to the original settings, it's just a single tap on the 'Reset to default' button. This way you go back to the original settings.

Question 48

How Do I View Call and Put Charts Together in Sahi Scalper?

Accepted Answer

When you're trading options intraday, watching only one chart at a time means you're always missing half the picture. A move in the call premium means something. A simultaneous move in the put means something else. Seeing both together  in real time, on the same screen gives you a much clearer sense of where momentum is actually sitting and which side of the trade is seeing more activity.
By default, Scalper loads with the spot chart alongside your selected call or put chart. But if you want to track both the call and put simultaneously, Sahi Scalper's Layout Selection lets you switch to a Call + Put view instantly, replacing the spot chart with the other side of the strike so both premiums are visible at the same time.
How to Enable Call + Put View on Mobile
Step 1 — On the Sahi home screen, tap on the index you want to trade to enter Scalper Mode.
Step 2 — Tap the three dots at the top of the screen.
Step 3 — From the menu, tap on Layout Selection.
Step 4 — Select Call + Put from the available layout options. Both charts will load on your screen simultaneously.
How to Enable Call + Put View on Web
Step 1 — Log in to Sahi Web. Scalper Mode opens automatically.
Step 2 — Look for the Select Layout icon at the top left of the screen.
Step 3 — Click on it and select Call + Put. Both the call and put charts for your selected strike will load side by side.

Question 49

How do I set a Stop Loss (SL) and Take Profit (TP) on Sahi?

Accepted Answer

Sahi gives you multiple ways to set a Stop Loss and Take Profit from the chart after you're in a position and automatically in Scalper mode.
Method 1 — From the chart (after entering a position):

Open the chart for the stock or contract where you have an open position.

Click on the position pill on the chart at the price level where you want your SL.

Select the ‘Stop Loss' (SL) pill and drag it to your desired place, and once you see the confirmation window, select the order type (Market/Limit) and click 'Apply.'

Repeat the same for your Take Profit (TP) price level.

Alternatively, drag the existing SL/TP order lines (shown on the chart) to adjust them.

Method 2 — Auto SL/TP in Scalper:

In Sahi Scalper, your default SL and TP values can be pre-configured in Order Defaults. When you execute a 1-tap buy or sell in Scalper, SL and TP are automatically placed at your default levels.

Click on the 3 dots at the top right corner, then go to Order Defaults.

Go to SL/TP and turn on the auto stop loss and auto take profit.

Then select a percentage or points to set the auto SL and TP.

Once confirmed, click on Apply, and the default settings will be applicable for all upcoming trades.

Note: SL and TP are linked orders. When one triggers and is executed, the other is automatically cancelled to prevent a double exit from the same position.

Question 50

How do I set SL and TP for large F&O positions that exceed the exchange freeze limit?

Accepted Answer

When your F&O position size exceeds the exchange's freeze quantity (the maximum size per single order), your SL and TP orders must also be split into multiple orders to match. Sahi handles this automatically.
How it works:

Place your large F&O position — Sahi automatically splits it into multiple orders, each within the freeze limit.

When you set an SL or TP for the full position, Sahi splits the SL/TP orders proportionally to match each sub-order.

All split SL/TP orders are linked — when one triggers, the others are adjusted automatically to reflect the remaining position.

Note: For very large positions spanning many split orders, monitor the Orders screen to verify all SL/TP splits have been placed correctly after entry. In fast-moving markets, execution of split orders may vary slightly in timing.

Question 51

What is a Trailing Stop Loss (TSL) and how does it work on Sahi?

Accepted Answer

A Trailing Stop Loss (TSL) is a dynamic stop loss that automatically moves in the direction of a profitable trade, locking in gains as the price moves in your favour, while still protecting you if the market reverses.
Unlike a fixed Stop Loss, which stays at one price level, a TSL trails behind the best price achieved since you set it:

As the price moves in your favour (up for a long position, down for a short), the TSL moves with it, maintaining a set distance.

If the price reverses by the set distance from the peak (for a long) or trough (for a short), the TSL triggers and exits your position.

The TSL never moves against you, it only adjusts in the direction of profit.

Example:
You buy a Nifty CE at ₹100 and set a TSL of ₹10. As the price rises to ₹130, your TSL moves up to ₹120 (₹130 − ₹10). If the price then falls to ₹120, your TSL triggers and you exit at approximately ₹120, locking in a ₹20 profit rather than risking a full reversal back to your original SL.
Note: TSL on Sahi functions as a trailing value in points (not percentage) for options in Scalper.

Question 52

How do I set a custom Trailing Stop Loss value on Sahi?

Accepted Answer

Sahi's Custom Trailing SL feature lets you define exactly how your stop loss should trail, replacing the platform's fixed default trail value with your own settings.
Where to set it:

Go to Profile → Order Defaults → SL/TP → Trailing Stop-Loss.

Alternatively, access it from the Order Defaults panel within Scalper (tap the 3 dots icon on the screen) and then click Order defaults → Sl/TP → Trailing SL.

What you can customise:

Trail value in points — how many points behind the best price the stop should sit.

How aggressively the stop should trail as the price moves.

When the TSL should start protecting profits (activation threshold).

Note: Once saved in Order Defaults, your custom TSL values apply automatically every time you use TSL in Scalper. You can still override them for individual trades by changing the value in the order panel before placing the order.

Question 53

How does the Trailing Stop Loss adjust as the price moves step by step?

Accepted Answer

Here is the precise mechanism of how TSL adjusts on Sahi:

Step

What happens

1. You enter a position and activate TSL

The TSL is set at: Entry Price − Trail Value (for a long position). Example: Entry at ₹100, Trail = ₹10, initial TSL = ₹90.

2. Price moves in your favour

As the price rises above ₹100, the TSL follows. At ₹110, TSL moves to ₹100. At ₹120, TSL moves to ₹110. And so on — always Trail Value behind the highest price reached.

3. Price consolidates or moves sideways

TSL stays at its last updated level. It does not move down if the price falls short of a new high.

4. Price reverses by the Trail Value

If the price falls from ₹120 back to ₹110 (and your TSL is at ₹110), the TSL triggers. A market or limit exit order is sent to the exchange.

5. Position exits

Your position is closed at or near the TSL trigger price. The linked TP order (if any) is automatically cancelled.

Question 54

How do I use Trailing Stop Loss for F&O positions?

Accepted Answer

While TSL is most commonly used in Scalper for quick options trades, you can also apply it on the charts from the positions.

Setting TSL from the chart (for existing positions):

Open the chart for your F&O position.

Tap on your existing SL order line on the chart, and move it to your desired position.

Check the 'Trailing stop loss' box to convert the fixed SL to a trailing SL.

Click apply, which will take your default TSL setting from your default TSL setting

Question 55

How do I configure default order quantities on Sahi?

Accepted Answer

Sahi's Order Defaults feature lets you set a default trade size that is automatically applied every time you open an order panel or initiate a 1-tap trade in Scalper, so you don't have to manually enter the quantity or lots each time.
How to set default quantities:

In Order Defaults: Go to Profile → Order Defaults.

Select 'Trade Quantity'.

Set default quantities for each instrument (e.g., Nifty50, SENSEX, etc).

Once done, tap Apply.

Note: Default quantities set in Order Defaults apply across all modes but it can be changed before executing the order.

Question 56

How do I configure default Trailing SL and auto SL/TP settings in the Order Defaults dashboard?

Accepted Answer

The Order Defaults dashboard on Sahi is a central control panel where you configure all your default trading behaviour, eliminating the need to set preferences before every trade.
How to access Order Defaults:

Go to Profile from the top right corner.

Tap Order Defaults.

What you can configure:

Default Quantity / Lots: Pre-set your standard trade size per segment.

Auto SL: Enable automatic Stop Loss placement on every new position, at a level you specify.

Auto TP: Enable automatic Take Profit placement on every new position.

Trailing SL: Set your default trailing SL trail value (in points). Once set, any trade where you activate TSL will use this value by default.

SL/TP Order Type: Choose whether SL and TP should be Market or Limit orders by default.

Tip: Once you have configured Order Defaults to match your trading style, you rarely need to change anything before a trade. This is especially powerful in Scalper, where every second counts and pre-configured defaults let you enter trades instantly.

Question 58

How do I open Scalper mode on Sahi?

Accepted Answer

Scalper is accessible directly from the main Sahi app interface — you do not need to navigate through multiple screens to reach it.
 
How to open Scalper:

Tap the Trade icon in the bottom navigation bar.

Tap on the top most tile of ‘Options Scalper 2.0

Alternatively, you can click any of the indices tabs on the home page, then tap 'Enter Options Scalper' from below the screen.

Note: Scalper remembers your last instrument, layout mode, and order defaults across sessions. You do not need to reconfigure on every login.

Question 59

How does 1-tap buy and sell work in Sahi Scalper?

Accepted Answer

1-tap Buy and 1-tap Sell is the core execution button in Sahi Scalper. When configured with an auto SL and TP, a single tap simultaneously places three orders:

Your entry order (Market or Limit, at your configured price preference).

Your Stop Loss order (at your configured auto SL level).

Your Take Profit order (at your configured auto TP level).

All three orders are sent to the exchange as part of one action. You do not need to place them separately.
What happens step by step when you tap Buy:

Scalper reads your current Order Defaults: quantity/lots, order type (Market or Limit), SL level, and TP level.

The entry order is sent to the exchange immediately.

Once the entry is confirmed (filled), the SL and TP orders are automatically placed at your configured levels.

Your open position appears at the bottom of the Scalper screen with live P&L updating in real time.

Important: 1-tap execution uses whatever quantity, SL, and TP are set in Order Defaults at the moment you tap. Always verify these before entering a trade, especially after switching instruments, as lot sizes differ between contracts.

Question 60

How Do I Choose Between Market and Limit for 1-Tap Orders on Sahi?

Accepted Answer

When you're in Scalper Mode and you tap Buy or Sell, the order goes to the exchange instantly. But how it gets executed and at what price depends on whether your 1-tap order is configured as a Market order or a Limit order. Getting this setting right for your trading style can make a meaningful difference to how your entries and exits actually fill.
A Market order executes immediately at the best available price at that moment. You get filled fast, but you don't control the exact price. This works well in highly liquid contracts like Bank Nifty where the bid-ask spread is tight and the risk of slippage is relatively low. If speed of execution matters more than price precision which is often the case during fast expiry moves , Market is the right choice.
A Limit order lets you define the price at which you're willing to buy or sell. Your order only executes if the market reaches that price, which means you have more control over your fill but no guarantee of execution. This is more useful in situations where you want to avoid paying a wide spread, or when you're entering a position in a slightly less liquid contract where the difference between bid and ask is large enough to matter.
When you select Limit as your 1-tap order type on Sahi, you also choose how the limit price should be calculated. There are three options — Best Bid/Offer, LTP, and Midpoint of Bid/Offer.
Best Bid/Offer sets your limit price at the best available bid or offer at the time of placing the order. For a buy order this means the best ask price, and for a sell order the best bid price. This gives you the highest chance of getting filled quickly while still placing a limit order rather than a market one.
LTP sets your limit price at the Last Traded Price the price at which the contract last changed hands. This is a common reference point for traders who want to enter close to where the market currently is without chasing the spread.
Midpoint of Bid/Offer sets the limit price exactly halfway between the current bid and ask. This is particularly useful when the spread is wide instead of paying the full ask on a buy or accepting the full bid on a sell, you're splitting the difference and potentially getting a better fill than either the bid or ask alone would give you.
Whatever you configure here becomes the default for all your future 1-tap trades until you change it again.
How to Configure 1-Tap Order Type on Mobile
Step 1 — You can reach this setting in two ways. Either open Scalper Mode, tap the three dots at the top, and select Order Defaults — or go to Profile → Order Defaults.
Step 2 — Open 1-Tap Order Settings Tap on 1-Tap Buy/Sell.
Step 3 — Choose Market or Limit Select your preferred execution type. If you choose Limit, you will also be prompted to select your preferred limit price method — Best Bid/Offer, LTP, or Midpoint of Bid/Offer.
How to Configure 1-Tap Order Type on Web
Step 1 — Click on the Settings icon next to the 1-Tap order button on Sahi Web.
Step 2 — Choose Market or Limit Under 1-Tap Buy/Sell, select your preferred order type. If Limit is selected, choose between Best Bid/Offer, LTP, or Midpoint of Bid/Offer as your limit price reference.

Question 61

How do I set my default price preference in Sahi Scalper?

Accepted Answer

Your price preference determines the order type used every time you tap Buy or Sell in Scalper. Set it once in Order Defaults and it applies to all 1-tap entries until you change it.
How to set your price preference:

In Scalper, tap the 3-dot menu icon in the top right corner.

Select Order Defaults.

Under Order Type, choose your preferred entry: Market, Limit – LTP, Limit – Best Bid/Offer, or Limit – Midpoint.

Tap Apply to save. This preference is now active for all 1-tap trades.

Note: You can also change the price preference directly from the Scalper main screen before placing a trade, look for the order type indicator near the Buy/Sell buttons without going into Order Defaults.

Question 62

How do limit order exits work in Scalper 2.0?

Accepted Answer

In Scalper 2.0, when your Stop Loss or Take Profit triggers, you can choose whether the exit order sent to the exchange is a Market order or a Limit order. This is configured separately for SL and TP in Order Defaults.

Exit Type

How it works

Trade-off

Market exit (SL or TP)

When the SL/TP price is hit, a Market order is sent to exit immediately. Execution is near-instant for liquid contracts.

Guaranteed exit, but fill price may differ from the trigger price in fast-moving markets (slippage).

Limit exit (SL or TP)

When the SL/TP price is hit, a Limit order is placed at or near the trigger price.

Better price control, but carries the risk of non-execution if the market moves quickly through your level.

In case of a limit order exit, when you select a price on the chart, your order gets executed at the same price with very minimum slippage, depending on the type of exit you have selected.

You can choose between ‘Best Bid/Offer’, which sends your buy/sell order at the best offer price.

Or select LTP, which sends the limit order at the Last Traded price.

If you select Midpoint of Bid/Offer, your order is executed at the midpoint  of bid/offer price, which is then rounded to the nearest tick size.

For Stop Loss: most traders prefer Market exits to guarantee they get out even in fast-moving conditions. For Take Profit: Limit exits are more common, since you are targeting a specific price and not reacting to adverse movement.
 
Note: Scalper 2.0 lets you set SL as Market and TP as Limit, or any combination. Configure this in Order Defaults → SL/TP Order Type. This was not possible in the original Scalper, which only supported Market exits.

Question 63

What is the Live Market Clock in Sahi Scalper and how do I use it?

Accepted Answer

The Live Market Clock is a visual display in Sahi Scalper showing a real-time countdown of time remaining in the current trading session. It is particularly useful for options traders who need to be aware of:

How much time is left before the auto square-off window begins at 3:20 PM for MIS positions.

How time decay (Theta) is accelerating as the session approaches close.

When to make carry-forward decisions if you want to convert a position to NRML before the session ends.

The clock is displayed prominently within the Scalper interface so you can monitor session time at a glance without leaving your trading screen or checking your phone's system clock.

Tip: For options buyers, the Live Market Clock is a constant reminder that Theta is working against you with every passing minute. Use it to set time-based exit rules for yourself, for example, exit any open position with 30 minutes or less remaining in the session.

Question 64

What are sync crosshairs in Sahi Scalper and how do I enable them?

Accepted Answer

Sync crosshairs is a feature in Scalper's landscape dual-chart mode that links the crosshair cursor across both charts. When you hover over or tap a candle on one chart, the corresponding time point is automatically highlighted on the second chart simultaneously.
Why this is useful:

Instantly see what each chart was doing at the same moment in time, without manually hunting for the same candle on the second chart.

Spot correlation breaks between the underlying index and the option premium at the same point in time.

Compare how a 1-minute move corresponds to the 5-minute chart at that exact moment.

Identify whether a price spike in one instrument preceded or followed a move in the other.

To enable sync crosshairs: while in landscape mode, look for the sync or link icon in the chart toolbar. Tap it to activate; both charts will now show the same crosshair when you interact with either one.
