I think what's really being asked is ''how do you know when price is about to start chopping aorund?''. (answer: I don't know. I don't think anyone does)
I mean, you can identify chop in realtime with your eyes, and when you see that moves either way seem unsustainable and longs and shorts are all being stopped out and price isn't going anywhere.
The problem is that this information is inevitably too late to act upon.
Once you realise you are in 'chop', you've already been stopped out a few times.
Even worse, once you have identified 'chop' you decide to stay out, and that's when you miss the big move! Or you decide 'Right, we're in chop. I'm gonna short move up and buy moves down. Bollinger band style trading'', and that's when it makes the trend move and you are stopped yet again![]()
Again, it depends on the plan. With mine, you're stopped out twice. That's it. This is, of course, assuming that one is entering the chop at all. If one is already in the trade, then there's a different management question: at what point do I exit the trade rather than ride it out? Again, this is a question answered by the plan. Everyone knows that traders take a breather during trend days before continuations. But it's up to the trader to determine what behaviors signal a range/consolidation and which signal a reversal. If the trader exits for some reason, he is then in a position of re-entering the trade as he would any other range. But, yet again, this is a question answered by the plan. If, for example, the trader doesn't know what a range is, he won't be able to recognize it. If he can't/doesn't recognize it, he won't be able to take advantage of a breakout from it.
There is no mystery here. It's just a matter of study, data collection, analysis, testing, implementation, none of which most traders bother with.
