That’s just planning to give 10% more to the market while planning that a miracle happens. If a trade goes bad, you need to close it. I would advise always having a Stop Loss in place to limit loss to a certain amount of your account (1% in my case, opinions vary but rarely advise more than 5% per trade), which then takes you out of a trade that has gone bad on you. You clearly did not do this, but you are still faced here with evidence that you read the market incorrectly and your trade has gone bad. Once you realize this, it is time to close the trade, whether you are 1% down, 40% down, 90% down, whatever. Always maintain an up to date view on whether any given trade still makes sense given the current market picture. If a trade suddenly makes no sense, trail your SL, cut your losses and close, whatever, but always be prepared to change your market view in an instant.
And obviously this point should come well before you hit anything like a 40% drawdown on a single trade, so you seriously need to stop live trading immediately until you have some form of risk management plan in place. If you can be 40% down on your account ([I]particularly [/I]on a single trade) then you should not be trading live as your system is fundamentally flawed and you will fail if you leave things as they are.
And the whole ‘I will close when I hit 50% down’ thing is crazy talk - that is chasing the market and using hope, rather than trading a strategy professionally. You’ll lose the rest of your account if you continue to trade in such an arbitrary, casual manner.
The secret to successful trading over the long term is mechanical execution of an effective strategy. If you can hit a 40% loss on an open trade then your strategy is not effective, and if you can even entertain the idea of holding until it hits a 50% loss just in case things reverse then you are not executing mechanically. So you need to address pretty much everything, imho.
I am sorry that this has been an expensive lesson, but it is a valuable one if it either a) makes you get a proper, rounded methodology in place or b) shows you that you are not cut out for this.
Trading as you are, think of taking the 40% loss as 60% saved rather than 40% lost - you could have blown the lot trading this way.
Hope you get back on the horse and come through this stronger for it.
