Because of the choppiness nature in futures (YM , ER2) <b>Too many participants.</b> a stop less then 7 ticks or so, will get stopped out even if you are right in the direction. They just love to run around your entry for fun. Not so in stocks.. Buyers/sellers protect their castles like their life depended on it. Once broken, hell breaks loose. That is why people lose more money in futures, risk control is harder. Stops have to be wider. Wider the stop, the pain hurts a lot more when you hit a drawdown. ps. I did not trade futures, just an observation from watching it constantly over the last year or so.
