I think someone calculated that one time I had a 42% dd. It was -219 pips. It depends on the account I suppose. The below account say Max DD was 46%.
You can view the highest and lowest DD by going to this account. It give you more data with respect to high/low trades and also how many pips a month my system gets.
I got this from the site above:
I trade the GBPUSD with over 98% accuracy. I am after 25 pips per trade with a stop loss of 250 pips. I will open only one trade at a time per direction. In some cases there will be a hedging situation but if you are unable to hedge then allow only one open trade at a time. Otherwise, please use maximum of TWO open trades and leverage about .10 cents per $100 in your balance. Please monitor your trades every day because your account is going to grow fast. I recommend leverage of 1:200 however, 1:50 will work but you need to probably risk only 5-7% per trade. I personally risk upwards of 60% per trade because of the great performance I have with this system. I am starting with a $100 in my account. My goal is to reach $2,000,000 in 2 years.
