What separates a real backtest from a comforting one
Costs charged in full
Brokerage, STT, exchange charges, GST, stamp duty and slippage for Indian instruments; spread, swap and commission for forex. Assumptions stated openly so you can challenge them.
No look-ahead bias
Signals evaluate on closed bars only. A test that peeks at the current bar's close to enter at its open produces a beautiful curve and a worthless one.
Sensitivity analysis
Parameters nudged ±20% to see whether the edge survives. If profit exists only at one exact setting, that is curve fitting, and you'll be told.
Walk-forward validation
Optimise on one window, test on the next, roll forward. The closest thing to an honest out-of-sample answer available before going live.
Full history, not a window
Tested across trending, ranging and crisis regimes — not the flattering three years that happened to suit the strategy.
Liquidity sanity checks
Options strikes and small-cap stocks that look profitable on paper often cannot be traded at those prices. Flagged where relevant.
Forex and global market backtesting
Different market, different traps. Spreads widen into news and at rollover. Swap charges accumulate on positions held overnight and can invert a positive expectancy on a slow-moving system. Broker execution varies enough that a strategy profitable on one feed is marginal on another. Forex tests run on the MetaTrader 5 Strategy Tester with real-tick data and modelled spread and commission, and are cross-checked against a second implementation where the result is close enough to matter.
Indian market backtesting — the specifics that matter
Backtesting NSE and BSE strategies has traps that generic tools miss. Transaction costs alone decide the fate of most intraday systems: brokerage plus STT plus exchange charges plus GST plus stamp duty is a real drag, and a backtest ignoring them will manufacture an edge from nothing. Expiry-day behaviour on Nifty, Bank Nifty and Fin Nifty is structurally different from the rest of the week and has to be modelled separately. Options strategies need the spread on the actual strikes traded, not a mid-price fantasy. And Indian data has its own quirks — corporate actions, contract rollovers, lot-size changes — each of which will silently corrupt a naive test.
What you'll be asked for
- The rules — entry, exit, stop, target, in whatever form they exist today.
- The instrument and timeframe — Bank Nifty 5-min, EURUSD H1, a stock basket.
- Position sizing — fixed quantity, fixed risk percentage, or something else.
- How far back — 3 years, 7 years, everything available.
- Your broker's cost structure, if you want it modelled exactly.
If any of that is still fuzzy, the specification stage exists precisely to sharpen it. Most traders arrive with rules that feel precise and turn out to have three unstated assumptions — finding those is half the value.

The honest limitation
A backtest describes the past. It cannot promise the future, and nobody credible will tell you otherwise. Regimes shift, liquidity dries up, and a system that worked for seven years can stop working in the eighth. What rigorous testing gives you is an honest estimate of edge, a realistic expectation of the drawdown you'll have to sit through, and evidence that the result isn't an artefact of fitting. That is the difference between an informed decision and a hopeful one — and it is worth paying for.
