Is your trading what it's supposed to be. At least mathematically speaking? It's all about the numbers. What I mean is that when a trade is placed the amount that is risked should be less than or equal to two time the amount thats expected to be gained. That for me would be the bare bones absolute minimum R/R I would use. Much more often than not I use 1:3 R/R and always higher when I can get it. Remeber the higher the R/R the less times you need to be right and still make a profit.
