Range-band volatility breakout
This intraday NIFTY futures system draws two levels each morning: today's opening price plus and minus half of yesterday's high-to-low range. Whichever level a one-minute candle closes beyond first decides the trade, long above and short below. The stop sits back at the open. It is the classic volatility breakout idea: if the market travels a meaningful share of yesterday's range away from the open, it may keep going.How it trades
Results
PRE-BUILT · DEFAULTSWhere it made and lost money
In this test the kind of session decided almost everything. On 64 trend days that closed near their high or low, the breakout made +₹3,78,919 with an 86% win rate, because a move that clears the band and never returns to the open is simply held to 15:15. On 46 choppy days it lost ₹2,49,931 and on 60 quiet sessions ₹94,256: price pokes through a level, swings back, and the stop at the open is hit. Flat openings made ₹61,548 over 115 trades while gap-up openings lost ₹20,758 over 25. Fridays did well and Thursdays poorly, but one year is too short to read much into weekdays.
About this strategy
- Before the session, measure yesterday's high minus low on the near-month NIFTY future.
- At 09:15 take today's open and set an upper level at open + 0.5 × that range and a lower level at open − 0.5 × that range.
- Watch one-minute candles; the first that closes above the upper level (having been at or below it) triggers a buy of one lot at the next tick, and a close below the lower level triggers a sell.
- Signals count only up to the 14:30 candle, and there is at most one trade a day.
- The stop loss is today's open; if the fill is already back through the open, the trade is skipped.
- A 4% target is set but is rarely reached intraday; whatever is open is closed at 15:15.
Why traders use it
Yesterday's range is a quick, self-adjusting yardstick for how far NIFTY normally travels in a day. A move of half that distance away from the open is read as real intent rather than noise, so the trade joins it. Using the open as the stop gives a natural line in the sand: if price returns there, the breakout has failed. The rules fit on a sticky note and need no indicators, which is why the method has stayed popular for decades.
The year in plain words
On NIFTY futures from 1 Oct 2025 to 30 Sep 2026 with default settings, the system made 170 trades and won 49% of them for ₹34,732 before costs, a profit factor of 1.07. The average win (₹6,005) was only slightly bigger than the average loss (₹5,462). The target never hit: 56 trades were stopped at the open and 114 ran to 15:15. February made ₹49,579 while June lost ₹36,335, and the maximum drawdown reached ₹59,215. After ₹20 per order and bid-ask slippage the year ends at roughly breakeven, ₹500, so the gross edge was almost entirely absorbed by costs.
What the settings do
Risks
- The stop at the open can be far from the entry on wide-range days, so a single loss can reach ₹14,800 per lot as it did in this test.
- Futures losses are not capped like bought options; a fast reversal can fill the stop well beyond the open.
- The profit before costs is thin, so brokerage, spread and STT on futures decide whether it makes money.
- Long losing stretches are normal: the drawdown of ₹59,215 was larger than the year's gross profit.
Who it suits
Traders comfortable holding one NIFTY futures lot intraday with a stop that may be a few hundred points away, who can accept coin-flip win rates and months that give back earlier gains.
Questions traders ask
What is a volatility breakout strategy?
It adds a fraction of the previous day's range to today's open to make a buy level and subtracts it to make a sell level. A decisive move beyond either level is taken as the start of a trend for the day. Here the fraction is 0.5, signals use one-minute closes, and the stop is the day's open.
Is the range-band volatility breakout profitable on NIFTY?
From 1 Oct 2025 to 30 Sep 2026 it made ₹34,732 before costs on one lot of NIFTY futures, but only about ₹500 after ₹20 per order and bid-ask slippage, with statutory charges still to come. The maximum drawdown before costs was ₹59,215. Past results do not guarantee future ones.
Why is the stop placed at the day's open?
The open is where the measurement began. If price falls back there after a breakout, the move that triggered the trade has fully reversed, so the idea is treated as wrong. It also means the stop distance grows with yesterday's range, giving bigger room on volatile days.
How often did the 4% target get hit?
Not once in this backtest. NIFTY rarely moves 4% within a session, so every trade ended either at the open-price stop (56 trades) or at the 15:15 square-off (114 trades). Lowering “Target %” changes the exit mix a lot.
