Quote from Ghost of Cutten:
That's not a mistake, that's a sign of completely irrational trading. IMO you should take a break from trading for a month and start an entire risk management plan from scratch. Otherwise you are just asking for your 100k loss to become a 400k+ one.
I'd suggest the following rules:
1. Never risk more than 1% of equity from entry to initial stop-loss on any single position.
2. Never risk more than 3% of open profit to trailing stop-loss on any single position.
3. Treat strongly correlated positions as one position.
4. If you are down >10%, cut all position sizes in half.
5. If you are down 20%+, get flat and revisit your trading and risk management to see what you did wrong.
Probably most important:
6. Have another person review your risk and size on a daily basis. It's clear to me you can't manage risk very well, and if you continue trading solo, I think you will blow up. Since the cost of blowing up will be at least 300k for you, you should be willing to pay someone part-time, maybe $500 a month, to monitor your positions and force you to stick to your risk management rules. Sort of like Odysseus being tied to the mast by his crew so he couldn't sail the ship towards the sirens.
