I find it hysterical when investing idiots on youtube go to someone's daytrading channel and tell them that they're risking too much of their capital. Shouldn't this rule only apply to investors & preferably with around 6 figures or more? This trader only had 2k in his account trades maybe 5-10 times a day. The commission he pays wouldn't make much sense to trade anything below 25% than say 3% or 1%. Original youtube comment : I still think that your position sizing is too aggressive. even if you define your risk before you entry the trade you should not risk more than 3% of your capitan in a single trade in fact Tom basso just risk 1% of his capital. I am pretty sure that if you are trading with more risk than what you should take you will get emotional easily. on top of that you should figure out what kind of fear did you feel on the trade. were you afraid of losing money? were you afraid of been wrong? were you afraid of missing out the opportunity? I know that you may think that you already know about trading but if i were you i would try to check out Mark douglas' How to think like a professional trader.
