Wow! Nice work on this trading system. The leverage used (1:100) is safe and everything else seems to be profitable. Good work.
The leverage is only a small part of safe forex trading. What is more important is how big are the trade sizes compared to the balance of the account. That's the biggest risk factor and this account is heavy on the risk side of the trading equation.
Your criticism is very vague and simplistic.
On 01 Jun my balance was $300,000 , and risk management is based on the account balance.
And that pin means Total volume of all trades, not The total volume at a time.
In 33 months of running, my system’s maximum drawdown is 9%, and its working fine.
