What it is
Momentum ignition is the moment a market goes from quiet to loud: a single bar with two or three times the recent average volume and a range well above recent bars, breaking a short-term level. This playbook enters on or immediately after that bar, rides the burst, and exits when the volume fades. The trade's premise is that the bar is the start of something, not the whole thing.
It is a fast, high-turnover playbook that suits index futures and momentum stocks in the first 90 minutes of the session.
The logic
Ignition bars are produced by large orders hitting the market at once: an institutional program, a news algorithm, a cluster of stops. The first bar is the ignition; the follow-through comes from momentum traders and short covering. Because the initial order was large, it frequently is not finished on the first bar, and participants who did not see it coming need a few minutes to react.
On the other side of your entry is whoever was passive at the level that just broke, plus anyone fading the spike. When the ignition is a one-off print, they are right and you are the top tick. When the order flow behind the bar continues, they are trapped and you ride their exits.
Setup rules
- Market: index futures, momentum stocks with average daily volume above 2 million shares, liquid crypto perpetuals. Not thin names, where a single print produces a fake ignition.
- Timeframe: 1 or 2-minute chart for the trigger; 5-minute for context.
- Ignition bar conditions: volume at least 2.5x the average of the prior 20 bars; range at least 1.5x the average bar range; closes in the top (or bottom) 25 percent of its range; breaks the high of the prior 10 bars.
- Context conditions: price is on the same side of vwap as the ignition direction, or the ignition crosses VWAP; no major scheduled news within the next 5 minutes (see economic-calendar).
- Time: first 90 minutes of the regular session, or the first 30 minutes of the london-session for forex and crypto.
Entry, stop, target
Enter on the close of the ignition bar, or on the first bar that ticks above its high if you want confirmation. Stop is at the midpoint of the ignition bar; if price returns there, the ignition has failed. Target 1 is one ignition-bar range above the entry; target 2 is two ranges or the next structural level.
| Item | Level | Notes |
|---|---|---|
| Ignition bar | 99.00 to 100.20 | Range 1.20, volume 3x |
| Entry | 100.20 | Close of ignition bar |
| Stop | 99.60 | Bar midpoint, risk 0.60 |
| Target 1 | 101.40 | One bar range, reward 1.20, 2R |
| Target 2 | 102.60 | Two bar ranges, 4R |
Time stop: if target 1 is not hit within 5 bars, exit; momentum that stalls is momentum that failed. Also exit if any subsequent bar prints volume above the ignition bar's while closing against the direction of the trade; that is the counter-order arriving.
Position sizing and risk
The stop is tight and the entry occurs after a fast move, so fills are worse than average. Risk 0.25 to 0.5 percent of equity per trade using /tools/position-size, and hold yourself to a maximum of three ignition attempts per session before stopping. The daily loss rules in /learn/risk-management matter more here than in slower playbooks because losses arrive quickly.
What breaks it
- Exhaustion bars. The identical bar occurs at the end of a move (a climax), where the huge volume is the last buyers, not the first. Context distinguishes them: an ignition happens from a quiet base, a climax after an extended run.
- Costs. The fill on an ignition bar's close is usually a tick or two worse than the print; that is 3 to 5 percent of the stop distance, every trade.
- Chop. In rotational markets ignition bars are followed by equally violent reversals. Expect win rates under 40 percent in low-volatility ranges.
- News spikes. A print reacting to headline news often ignites and reverses within a minute. Avoid ignition bars caused by scheduled data.
- Edge decay. Volume-spike detection is trivial to automate and is widely automated. Your edge, if any, is in the context filter and the exit discipline, not in the trigger.
How to test it
Script the ignition-bar definition and run it over 12 months of 1-minute data on 3 to 5 instruments. For each signal, record the forward maximum favourable and adverse excursion over the next 10 bars in units of the ignition bar's range. This gives you a distribution to design exits around before you fix any exit rule. Then apply your rules and compute expectancy and profit-factor with realistic slippage of one tick per side. Minimum 400 signals; ignition bars are common, so this is achievable. Follow with 20 sessions of simulated execution to confirm you can actually get the entry price your backtest assumes.
Variations
- Ignition retest: wait for the first pullback to the ignition bar's high and enter there with a tighter stop.
- Delta-confirmed ignition using a footprint chart to require the bar's delta to match its direction; overlaps with scalping-the-dom.
- Opening ignition: the first ignition bar of the session, which frequently coincides with the opening-range-breakout.
