This is cannonballing:
I did that in demo account a few months ago. I'm not willing to put enough funds in my live account to use a strategy like that. It worked in demo because I had $10,000,000 fake dollars to fall back on. I only put $10,000 in my live account.
one thing I can see going wrong in my live account is that I'm trend following, but all my trades are kind of related. For example, selling eurusd while buying usdchf. It's just a different way of saying a very similar bet.
