Risk/reward ratio (which is really reward/risk) is meaningless to me. Market doesn't know or care, so why should I.
Put a trade on, stop in place and let price action do the rest. Where I will exit (with a profit or loss) price action will determine.
Not some silly R/R factor.
edit: just now see your post above mervyn which I agree completely with.
How do you stay patient in situations where maybe you are repeatedly scalping out too soon or holding winners too long? Like for example, I will maybe scalp out too fast on a few trades that end up running to my "best case scenario" targets, and then I convince myself to hold the next winner for those bigger targets, and then I get a string of trades where I should have taken profits faster. This tends to lead to me overtrading and taking trades that make no sense because I eventually start wanting to "take action" to make up for those inefficient exits especially once a few losses enter the mix as well.
to the no-indicators crowd) for most of my entries which also give me my stop loss spots. Of course I can't say I never get impatient but I've done it enough times, enough years, to just let things do what they will do.
