But look at it this way. R:r of 1:2 is ambitious for short-term trades. By using very tight stops you make it very likely they will be hit. It is twice as easy for price to hit a stop 10pts away as for it to hit a TP 20pts away. And don’t forget the spread. If mid-price is 1000 and there is a 2pt spread, you will enter long at 1001 and your stop will need to be at 991. On a 2pt spread, 991 will be triggered after only an 8pt price fall to mid-price 992. On the other side, for your 1001 long to make a 20pt profit you need price to rise to mid-price 1022 so you can exit for 1021. This makes your targeted risk:reward ratio actually an even more ambitious 8:22, nearer 1:3 than 1:2, and effectively an 8pt stop is very easy for price to take out.
If your entry is based on TA, let’s suppose you rank your entries and this one scores 70% for quality of signal. Pretty good. But when you exit at +20pts maybe the TA is now +75% or +80% or +100%. Makes no sense to exit a position that shows great TA in your favour.
