Am new here, and with my little knowledge am sure a good trader should have all the patience he/she can get.
Patience is needed, you have to be patience in terms of lost, trading is not always about benefits at all times, you will always run into lost a lot and that might trigger you to want to back out, but with patience you can scale through.

Another thing is discipline,  by disciplining yourself you will have the enablement to purse a goal you have set, and it will help you to be forced at all times.
Trading is a lose and gain thing if you aren't making profit you have to quit.
