Don't underestimate yourself.

It's perfectly OK 'not feeling sure' (me neither), but for that reason, it's important to document all the If's and proceed of action when XYZ happens. Smart traders act like this and it' exactly what I'm trying to do.

If you trade with 10$, 100$, 1000$ or 1M$ a 1% move is the same percentage. IMHO the greatest traders out there learnt to make this with very vast amounts and still sleep well at night.

Good luck out there. Wish you all the best also.
