Good point, but the thing is, we never know when the market will switch from choppy to trendy. Days are not all choppy or trendy. A day might be choppy in the morning and trendy in the afternoon. So if you stop after a win in a morning choppy market, you might miss the trendy market in the afternoon.You should have a logical basis to decide on what to do.
This example is based on fictitious figures.
If you have a 8 points profit it is not bad to get out if the market is not very trending. Only 5% of the profitable trades reach 8 points. 95% of the profitable trades never reached this level.
I would base my decision on the (hypothetical) table below. But only in non trending markets.
