You say use pure PA to enter the market, you still need entry criteria, why would you enter when you do? Based on what?
Well you could use price action like PIN bars, enter at close of PIN, SL 1 tick beyond high/low of PIN. That would be price action only. That's a 5 minute chart, I have found nothing to suggest that longer timeframes are much more reliable. The other problem with trading longer time frames is that you will have bigger draw downs and they will last longer. Who cares if you have to work harder, would you rather work hard and make money or take it easy and not make money?
