Anyone who day trades options in India knows the frustration of watching a profitable position turn into a smaller gain—or even a loss—the moment you hit the exit button. The culprit? Wide bid-ask spreads that eat into your mark-to-market (MTM) profits when using standard market orders.

Sahi’s trading platform addresses this problem by letting you exit positions at either the best bid or best offer price, depending on whether you’re selling or buying to close your position. This feature gives day traders control over their exit prices without the slippage that typically comes with market orders.

Understanding the Spread Problem for Day Traders

When you buy an option, you pay the ask price (the higher price sellers are willing to accept). When you sell, you receive the bid price (the lower price buyers are willing to pay). The difference between these two prices is the spread, and it represents an immediate cost to your trade.

For day traders working with tight profit margins, this spread can be devastating. Your position might show a decent profit on screen, but if the bid-ask spread is wide, hitting a market order to exit could instantly eat into those gains. This happens because market orders execute at whatever price is available, which for a sell order means the best bid price, not the LTP your P&L calculation is showing.

The problem intensifies during volatile periods, in illiquid option strikes, or during weekly expiries when spreads can widen significantly. Your MTM shows green, but the actual exit price tells a different story.

How Sahi’s Best Bid/Offer Feature Works

Sahi solves this through its One Tap Orders functionality with customizable price settings. Here’s how it works in practice:

For selling (exiting long positions): You can set your exit order to execute at the best offer price instead of the best bid. This means when you’re closing a position you bought, your sell order is placed at the ask price where other buyers are willing to purchase. While this doesn’t guarantee immediate execution, it significantly reduces the slippage compared to accepting the lower bid price.

For buying (exiting short positions): Similarly, when closing a short position, you can configure the system to place your buy order at the best bid price rather than paying the higher offer price.

To set this up, navigate to the Scalper’s three-dot menu, select Order Defaults, then One Tap Orders, and choose “Limit” with your preferred price option—either Best Bid Offer, Last Traded Price (LTP), or midpoint pricing. Once configured, exiting becomes a single tap: click the position and select “Exit.” The system automatically places your limit order at your chosen price setting.

Real-World Impact on Your Trading P&L

The difference between exiting at the best bid versus the best offer can be substantial, especially when you’re taking multiple trades throughout the day. When spreads are tight, the impact might be minimal. But during volatile market conditions or when trading less liquid strikes, that spread widens considerably.

With a standard market order on most platforms, your sell order executes at the best bid price—the lower end of the spread. This immediately reduces your realized profit compared to what your screen was showing based on last traded price.

With Sahi’s best offer setting, your exit order is placed at the ask price instead. If another buyer takes it, you capture a better exit price. Even if you need to adjust down slightly for faster execution, you’re still better off than the automatic fill at the bid that market orders give you.

This difference compounds across multiple trades throughout the day. Active day traders taking numerous positions can see these small slippages add up to significant amounts over weeks and months.

Additional Features for Day Traders

Beyond the customizable exit pricing, Sahi offers several tools designed specifically for fast-paced intraday trading. The platform includes keyboard shortcuts for rapid order placement, chart-based trading that lets you enter and exit directly from price charts, and automatic large order slicing to prevent market impact on bigger positions.

The Sahi’s Scalper interface provides a single-screen experience where you can monitor open interest, put-call ratios, and Greeks without switching between multiple windows—critical when you need to make split-second exit decisions.

The platform charges ₹10 per executed order for F&O trades, with the first 30 days free. This pricing is more favorable than the standard ₹20 per order charged by established brokers like Zerodha, Upstox, and Angel One.

How Traditional Platforms Handle Exits

Other popular Indian brokers support limit orders, but they require manual intervention. You need to open the order window, check the current order book, identify the best bid or offer price, manually enter that price, and then submit the order. During fast-moving markets, by the time you’ve completed these steps, prices may have already changed.

This manual process also increases the cognitive load when you’re managing multiple positions simultaneously—a common scenario for active day traders. The extra seconds spent placing each exit order can mean the difference between a profitable day and a losing one.

The Bottom Line for Day Traders

For day traders working in the Indian options market where spreads can quickly erode intraday profits, having control over exit pricing isn’t just convenient—it’s essential for protecting your MTM. Sahi’s automated best bid/offer exit feature removes the friction from closing positions while giving you the flexibility to choose execution at prices that preserve your profits rather than giving away money to the spread.

The ability to configure this once and then execute with a single tap makes it practical for high-frequency trading styles where every rupee matters and every second counts.
