received advert for this signal service in my inbox. Boasted that they banked 3,300 pips in 7 months.

lucky i bothered to come to myfxbook to look at their statement. What rubbish signal service to give you a drawdown of 73%. And yes they banked many pips but they also did not disclose that their negative floating pips is higher.

Please do not be deceived. Definitely not service by 'elite' traders.
Backtests are worthless, markets will never behave the same way. Do a forward test!
