Quote from J.Joseph:
80%! That's phenominal. I remember the days when I used to lose like that on my $500 practice account. It was still emotionally devastating regardless of the fact that I only lost hundreds at a time. But I eventually learned that a 5% loss with a second attempt the next day or two days later was more profitable than the "hold 'n' hope" method.
But seriously, manage your losses, and the wins will take care of themselves. There's a book on here that I recommend. "Trading for a Living" by Alexander Elder. Here's an exerpt from page 167 and 168
"Extensive testing has shown that the maximum amount a trader may lose on a single trade without damaging his long-term prospects is 2 percent of his equity. This limit includes slippage and commissions. If you have a $20,000 account, you may not risk more than $400 on any trade. If you have a $100,000 account, you may not risk more $2000 on a trade, but if you have only $10,000 in your account, then you can risk no more than $200 on a trade....The 2 percent rule puts a solid floor under the amount of damage the market can do to your account. Even a string of five or six losing trades will not cripple your prospects."
Elder is very right. I also suffered 3 back to back losses during the time you were suffering your 1 gigantic loss.It wasn't a good month for me as I was in denial over the whole thing far longer than I should have been. The difference is that my losses were small and I went on to end my 4th trade with positive 7% account growth. My last trade not only wiped out my 3 losers, but it gained an additional 7%.
The idea of going into a trade without knowing before hand how much I will lose if I'm wrong (and visualizing my account with that new, lower, amount to see if my emotions are okay with it) is just unfathomable.
I wouldn't worry too much about recovering from this loss. I would change my focus to long term survival (loss management) and a strategy that doesn't depend on being right on any given trade.
