I can understand why but wouldnt shrinking the risk be counter productive assuming R:R are related, you wont be using the extra capital?
To be honest. It all depends on your capital. Risking 5% on 100$ isnt gonna break the bank most of the time and for a bit of experience is ok. To be honest i dont risk more than 0.5% most of the time, because i trade enough to make enough gains over the course of the year.
