Had only 20% win rate today and missmanaged 1 trade with too big position which took me down -42% of daily loss allowance

Couldn't find my rhythm today and although 4 of 5 were losers, my winner ran big and my mistake was i took too big of size on my 1big loser for the stop i placed.  Easily detectable with hindsight.  Few of the trades:

GMCR - Long but got shaken out

MUR - Long off double bottom that failed

FNSR - Great scalper lately, long again for nice gain
