DislikedTrading without SL is possible and it gives good results. But you can lose all your money if the market collapses very active against you. Example CHFIgnored
Once I forgot to set SL and next time I looked to terminal - it was about 300$ in loss.
Then by my luck trend went back to my direction. I even got a nice profit (as I chose the right trend from the beginning).
But stress that I got was really huge.
This was my first and last time without SL.
