Increase size will increase the anxiety and more unwilling to cut loss, but if i don't, how do i increase my profit? But on the other hand, increase size will also cause bigger losses... More over, it is dangerous in current volatile market So do i open many positions? but too many positions cause one to lose focus, and lose money? Focus on one stock and put on big size? again, it can also lead to disaster if that stock underperform Now watching my account like a hawk ever since i recover my 20% loss in my account, am i becoming afraid of taking risk? or am i correct to be watching over my account rather than taking unnecessary risk? Should i be satisfied to be winning small profit everyday?
