I'm still trading my $100 Forex Experiment and I'm almost back to break even now after the EURUSD selloff. I lost about 15% of my account value from the last EURUSD high as I held onto my positions and sold them on the way down. In hindsight I should've kept them all but fear got the best of me and I was nearing the dreaded margin calls.
My last Forex trading plan used a "no stop" rule, which I'm going to change back to a "every position must have a stop" rule. This time, the stops will be placed strategically based on volatility calculation to avoid being whipsawed out of them.
