Relative-volume breakout
BreakoutIntermediate
Relative volume compares this bar's volume with the usual volume for that time of day or that lookback. A breakout rule asks price to leave a range only if volume is also unusually high. The volume check is there to ignore drifts that happen on an empty tape. It does not say how long the breakout will last.
Not investment advice. Nothing here is a recommendation to buy or sell anything. Backtests and historical studies are not guarantees, and a rule that worked in one sample can fail in the next. Trading can lose money. Links are for education, not endorsements. Do your own research.
- Rules
- Compute relative volume as this bar's volume divided by the average volume of the same bar over the past 20 sessions, or divided by a simple 20-bar average on a daily chart. Buy a close through a stated high, such as the prior day's high or a 20-day high, only when relative volume is above a threshold such as 1.5. Stop below the breakout bar. If volume is ordinary, skip the break.
- Where AI fits
- AI can align intraday volume with the correct time-of-day average, which is the detail that makes relative volume different from a raw spike. It can test the threshold on a training set. It should not treat a news headline plus a volume bar as confirmation unless the rule says so in advance.
- Markets
- Stocks and futures with consolidated volume. Avoid assets whose volume is mostly off-exchange or unreported.
- Timeframes
- Intraday with time-of-day normalization, or daily with a 20-session average.
- Risks
- News volume is not the same thing as sponsorship. A volume spike can be the exhaustion print. Thresholds are easy to fit. Index rebalances and options expiration inflate volume without a breakout you can hold.
