In my opinion if you need to trade with a 300 pip stop you need to stop trading.
Any signal provider on Zulutrade who opens 16 identical positions ALL of which are losing and racking up a 4000 pip drawdown is NOT a forex trader he/she is just a gambler.
ZuluGuard is an excellent feature on ZuluTrade but it should be used to maximize a traders trade recommendations not safe guard your account from his trades. If your s.p. is risking your account then follow someone who doesn't risk your account.
The (live) account that I use to post signals only opens 4 positions at any one time and every trade has a 40 pip stop plus spread.
My lot sizing is small - 0.03 lots per trade. That equates to about .21p per pip so the maximum exposure per trade is about £8.50. That's the maximum exposure. Most of my stops use a 10 pip stop or less because of my method. Of my last 30 trades on Zulu my maximum pip low is 27.
I do this because it means anyone can open a trading account with £500 and you can sleep easy at night KNOWING I'm not going to run up a huge drawdown and empty your account as has happened recently with the number 1 ZuluTrader Pamm deposit.
My s.p. account is currently running at 53% on a £500 deposit 6 months ago and its safe.
If you have a £5000 account then scale up the 0.03 lot sizing to whatever size you are comfortable with - your risk will be exactly the same.
Money management is key to forex trading.
If you understand m.m. then you wont have sleepless nights worrying about someone trading your account to extinction.
