Sahi and OptionX are built for different ends of the same market: active options traders in India who want serious tools and low costs.
Sahi is an all-in-one broker and trading terminal. At Rs. 10 per executed order, it is one of the lowest flat-fee brokers in India. The Sahi Scalper 2.0 is a well-built execution interface with dual charts, AI-powered indicators, embedded options chain, trade-from-chart execution, and auto trailing SL. For traders who want a single account that does everything, Sahi offers that at low cost.
OptionX is a professional trading terminal that connects to your existing broker. It is built for traders who need capabilities beyond what any broker's own terminal provides: combined-premium spread execution for multi-leg strategies, MTM Profit Protection and MTM Trailing at the portfolio level, a kill switch that exits all open positions, GROT grid automation, free paper trading forever, and 16 configurable widgets in a drag-and-drop workspace.
The verdict: Sahi is a strong choice for traders who want fast execution, low brokerage, and AI-assisted analysis in one account. OptionX is the right choice for options traders running multi-leg strategies who need execution precision that reduces inter-leg slippage, portfolio-level risk controls that Sahi does not have, and free paper trading to test strategies before risking capital.
The Core Difference
Sahi is a broker first. It holds your demat account, routes your orders to the exchange, and charges brokerage. The trading terminal and Scalper are features built on top of that broker relationship. You cannot use Sahi's terminal with another broker, and you cannot use OptionX directly with a Sahi account.
OptionX is a terminal first. It has no brokerage relationship and holds no funds. It connects to your existing broker account via OAuth API, routes orders through your broker, and handles execution, analytics, risk management, and automation at the terminal level. You need an account with one of OptionX's 19 supported brokers (Zerodha, Upstox, Fyers, Dhan, Angel One, Kotak, IIFL, Flattrade, AliceBlue, Rupeezy, Choice, Jainam, MStocks, and others) to use OptionX.
The practical consequence is that these are not interchangeable. Choosing Sahi means using Sahi's brokerage and Sahi's terminal together. Choosing OptionX means opening or using an account with a supported broker and paying both the broker's brokerage and OptionX's monthly subscription. The trade-off is between Sahi's lower all-in cost and OptionX's deeper execution and risk management capabilities.

What Is Sahi?
Sahi (operated by Aaritya Broking Private Limited) is a SEBI-registered discount broker founded in 2023 by ex-Swiggy CTO Dale Vaz and ex-Kotak Securities VP Manish Jain. It targets active F&O and stock traders with a technology-first trading experience. Sahi is registered with NSE, BSE, and CDSL, and has attracted over 400,000 app downloads since its December 2024 launch, backed by Accel and Elevation Capital.
Brokerage is flat Rs. 10 per executed order across all segments, with the first 30 days free and zero lifetime demat AMC. The platform is available as a mobile app (iOS and Android) and via a web terminal at web.sahi.com.
Sahi Scalper 2.0, the platform's primary execution interface for options traders, includes:
- Dual and multi-chart layout: Index chart, CE chart, PE chart, and options chain in one view
- Trade-from-chart execution with tap and drag for SL and TP placement
- Auto SL/TP on every entry (Market or Limit exit types)
- Customisable auto trailing SL with activation threshold and tightness controls
- Embedded live options chain with OI, OI change, and Greeks
- AI-powered indicators: Key Levels, OI Profile, OI Support/Resistance
- 20+ real-time stock scanners
- Super Alerts for price and candle pattern triggers
- Sahi Pulse (picture-in-picture P&L float while multitasking)
- In-house proprietary charting engine (60% faster chart rendering claimed)
What Sahi does not have: combined-premium spread execution, MTM Profit Protection and MTM Trailing at the portfolio level, GROT grid automation, a traditional price ladder (DOM), and paper trading. Sahi's kill switch pauses new order placement to prevent overtrading; it does not exit existing open positions. Portfolio-level risk controls are not part of the current feature set.
Sahi does not currently offer a public API. Third-party algo integration via TradingView, Amibroker, or custom code is listed as a future roadmap item.

Options Analytics
Both platforms provide a live options chain with Greeks, and both include a strategy builder with payoff diagrams. For basic options analysis during trade execution, either platform covers the fundamentals.
Sahi has a genuine advantage in AI-assisted analysis. The 20+ real-time scanners, AI Key Levels indicator, OI Profile, and OI Support/Resistance zones are built directly into the charting engine. For traders who rely on scan-driven workflows (finding setups across multiple instruments, monitoring OI shifts), Sahi's scanner infrastructure is more developed than OptionX's.
OptionX covers the analytics that options strategy traders need. Dedicated IV charts track historical and current implied volatility to help time entries. OI charts show open interest shifts across the chain. The strategy builder shows real-time combined Greeks and P&L across all legs of a position. These are the tools relevant for options sellers and spread traders who manage positions based on portfolio-level data.
Execution and Order Management
Sahi uses trade-from-chart as its primary execution model. You drag SL and target onto the chart, tap to enter, and the platform manages the OCO logic. The in-house charting engine is fast, and the Scalper 2.0 keyboard shortcuts make repetitive single-instrument entries efficient. Auto SL/TP and customisable trailing SL are well-implemented at the per-position level.
The gap appears with multi-leg strategy execution. Sahi's strategy builder lets you design and deploy multi-leg strategies, but each leg is executed as a separate order at the current market price. If you are executing a straddle and the CE fills 10 seconds before the PE, the premium on the PE has likely shifted. You receive a worse combined entry than you targeted.
OptionX solves this with the combined-premium spread ladder. You set a target net premium for the entire multi-leg strategy and execute it as a single unit. The platform manages the inter-leg timing to achieve the specified combined premium, reducing the slippage that comes from legging into spreads manually. For options sellers who trade straddles, strangles, and iron condors regularly, this capability changes the quality of every entry.
OptionX also provides a traditional price ladder (DOM) for scalpers who read order flow and want precise bid/ask entry. Sahi's chart-based execution does not show a price ladder, so order flow analysis at the DOM level is not available on the platform.
Risk Management
At the per-position level, Sahi and OptionX are comparable. Both offer auto trailing SL, auto SL/TP on entry, and partial exit capabilities. For directional scalpers managing one or two positions at a time, either platform handles position-level risk adequately.
Portfolio-level risk management is where OptionX has no equivalent on Sahi. MTM Profit Protection monitors the combined P&L of all your selected positions. When your portfolio reaches your defined profit target, it squares off everything automatically. MTM Stop-Loss does the same on the downside. MTM Trailing then locks in a portion of gains progressively as your portfolio P&L moves in your favour.
For options sellers running straddles or multi-leg positions, per-position stops alone are insufficient. Individual legs can move against you temporarily while the combined position remains profitable. Setting per-leg stops to protect against temporary adverse movement leads to premature exits. MTM controls at the portfolio level let you define risk in terms of what actually matters: total position P&L.
The kill switch distinction is important. Sahi's kill switch pauses new order placement to prevent overtrading. This is a useful feature for traders who overtrade under pressure, but it leaves existing positions open. OptionX's kill switch exits every open position across all strategies in a single click. In a fast-moving adverse market, the ability to close everything immediately is a different category of protection.
Automation
Sahi's strategy builder supports multi-leg strategy execution and modification, including one-tap add, modify, and exit of individual legs during a live trade. This is useful for adjusting positions in real time. However, Sahi currently has no public API, which means integration with external algo systems (TradingView signals, Python-based automation, Amibroker) is not possible. API access is on the roadmap but not yet available.
OptionX includes GROT (Grid Order Trader) on all plans. GROT places and manages a grid of buy and sell orders at defined price intervals on any instrument, running automatically within the OptionX workspace alongside your manual trading. No external tool, no coding, and no separate subscription are needed.
OptionX's automation works inside the same terminal where you trade. MTM controls, trailing SL at the portfolio level, and strategy-level time and price-based rules all operate from one interface. For traders who want to combine manual active trading with automated risk management and grid strategies, this integration is the practical advantage over building separate systems.
Paper Trading
OptionX paper trading is free forever on all plans. You get Rs. 5 Cr in virtual funds with no time limit. The paper trading environment is the same interface as live trading: the price ladder, combined-premium spread execution, MTM controls, GROT, and all 16 widgets work identically in paper mode. Moving from paper to live requires only switching the order routing from virtual to your broker API. There is no cost difference and no feature restriction.
Sahi does not currently offer a paper trading mode. The first 30 days of live trading are brokerage-free, which reduces the financial cost of early errors, but this is not the same as a risk-free practice environment. Trades during the free period are real orders with real capital at risk. Traders who want to test a new options strategy, learn the platform mechanics, or practice execution before committing meaningful capital do not have a dedicated virtual environment on Sahi.
For new options traders or experienced traders moving to a new strategy, paper trading at zero cost and with realistic execution conditions is a meaningful practical benefit. OptionX is one of the most generous paper trading offerings in the Indian market, available from day one.

Try OptionX FreePricing: All-in-One Broker vs Professional Terminal
Sahi's pricing model is straightforward: Rs. 10 per executed F&O order, zero account fees, and a free terminal. For traders who execute 100 F&O orders per month, the total platform cost is Rs. 1,000. This is among the lowest all-in costs for an actively trading retail F&O trader in India.
OptionX's pricing is a subscription on top of your broker's brokerage. At Rs. 999 per month for the Premium plan or Rs. 3,999 for Pro, you are paying for the terminal layer separately from your trading costs. A trader on OptionX using Zerodha (Rs. 20/order) executing 100 F&O orders per month spends Rs. 2,000 in brokerage plus Rs. 999 or Rs. 3,999 for the terminal, totalling Rs. 2,999 to Rs. 5,999.
The cost difference is real and favours Sahi for high-frequency traders on a cost basis. The question is whether the OptionX capabilities (combined-premium execution, MTM controls, GROT, paper trading, 16 widgets) justify the premium for your specific trading workflow.

Prices as of February 2026. OptionX requires a separately funded broker account. Sahi is an all-in-one broker and terminal. Verify current rates at optionx.trade/pricing and sahi.com/pricing.
For options sellers and multi-leg strategy traders where execution quality on spreads and portfolio-level risk management directly affects P&L, the combined-premium spread ladder and MTM controls can recover a month's subscription cost in avoided slippage and better-timed exits. For directional scalpers trading one leg at a time, Sahi's lower cost structure is harder to argue against on purely financial grounds.
Broker Support
Sahi is a standalone broker and terminal. The platform is only available to Sahi account holders. There is no multi-broker support and no ability to use the Sahi terminal with a different broker.
OptionX connects to 19 brokers: Zerodha, Upstox, Fyers, Dhan, Angel One, Kotak Securities, IIFL Securities, Flattrade, AliceBlue, Rupeezy, Choice, Jainam, MStocks, and others. All connections are via OAuth API. You can link multiple broker accounts and switch order routing between them from the same workspace.
An important clarification: OptionX does not currently integrate with Sahi. If you are considering OptionX, you would need an account with one of its 19 supported brokers. Sahi accounts cannot be connected to OptionX at present.
Final Verdict
Sahi is a genuinely well-built platform for its target audience: active options scalpers and F&O traders who want fast execution, AI-assisted analysis, and low brokerage in one account. The Rs. 10 flat brokerage is among the most competitive in India. Scalper 2.0's dual charts, embedded options chain, and customisable trailing SL are solid for the single-instrument scalping workflow. If your primary need is directional scalping with excellent cost efficiency, Sahi is a credible choice.
OptionX is built for a different level of trading complexity. Combined-premium spread execution, MTM Profit Protection with trailing at the portfolio level, a kill switch that actually exits positions (not just pauses new orders), GROT grid automation, 16 configurable widgets, and free paper trading are features that Sahi does not currently offer. For options sellers, spread traders, and position managers who deal with multi-leg strategies and portfolio-level risk, these are not optional capabilities.
The decision comes down to your trading profile. If you scalp single options legs, want the lowest possible all-in cost, and do not need portfolio-level risk controls or combined-premium execution, Sahi's offering is strong and cost-efficient. If you trade options strategies, manage multiple positions simultaneously, and need execution and risk management tools that go beyond what any broker's own terminal provides, OptionX is built for that workflow.
Start with OptionX's 7-day Pro trial to test the execution and risk management capabilities against your current workflow. Free paper trading is available from day one with Rs. 5 Cr in virtual funds, with no credit card required to start.
