The 900 pips loss in open positions are correct, but the other values are wrong. Z12 is winning money also this year and the grid trading method is currently at 3100 pips, not 1600 pips. You've probably looked at the Zulutrade system, but that's a simplified variant for Zulutrade specific reasons. But even that one has doubled the capital meanwhile. We also don't have records on myfxbook.Right, probably have something to do with options expiry on friday ?
But according to myfxbook your spectral filtering method z12 is loosing money this year.
And your grid method is showing 1600 pips profit but -900 pip loss in open positions.
What real hard cash are you talking about ?
As to the 900 pips open positions, our professor can probably better explain than I why relatively large negative open positions are typical for a grid trader. This is due to the mean reversion basis of this method. The important factor for your money is the equity, not the open positions.
