What is a rocket? Rocket is not a breakout, because breakout good be one bar, but rocket is multiple bars including a breakout.
Now, many people enter immediately after a breakout or some wait for retracement to see others supporting that breakout.
Rocket other hand you see people have taken position before you in one minute or 5 minute period chart, and driven price to overbought condition (calculated by stoch and macd, etc). So, your expectation is rocket would continue in a steep angle (you decide which slope is a rocket), but if rocket fails, which happen many times; you do wash trade or take a small loss. I mean, if it is a rocket, money velocity should continue not stall (that is where practice comes handy with log).
I do not take reversal with all failed rockets, there are criteria. After a wash or small loss, wait for a breakout bar with increase or dryup in volume. This is not a mechanical trading system, part of it discretionary. Only, through practice and experience plus keeping notes of your trading can make you a better trader (also, you need enough funds to survive, when you are in drawdown, and everybody goes through drawdown).
Certain time of the day, like early morning for rocket, then mid morning for reversal, no trade in lunch hours, then again in the evening look for rocket.
Also, subcribe to live news service for protection. Keeping your funds intact year after year is more important than big wins. That way you can battle another day. Good Trading.
