Update:
System One is sitting on about $100 of drawdown, nevertheless largely GBP pairs. When it doesn't improve I will restart this system a week.
System Two has a combined profit of approximately $16,000, about $9000 in one account and $7000 from the other. I've got rankings, about $12,000 profit in my short negative and $8000 reduction on my side, so that is intriguing. Exotics are large contributors. Complete margin required is about $400,000, so I don't believe you could do this by less than $1,000,000.
The hardest part of both of these ideas is determining exit, and it's probably why I wouldn't go live with either one of them. It's too hard to track this many pairs, and establishing an exit based on profit doesn't make sense. If I leave now, with $16,000 in profit? Imagine if it goes up? Imagine if it goes down? I don't have any idea if this is a place or not.
Probably I'll keep this on demonion for a few months and see what it will. My guess is that a few currencies induce the market. Already I can see that at one account I'm short both EUR and USD for approximately $2.5MM each, and the other is short EUR by $1.7MM, short USD by $800K and long JPY by $1.4MM. My guess is that I'm trading risk aversion that tends to adjust on a monthly cycle, and so that gives me 3-4 chances to grow winners prior to closing the grids and restarting.
IN OTHER NEWS....
My demonion JPY basket, previously closed up 79%, is now 88 percent over Jan 6 start with open transactions. It was my system to date. I'm concerned about more than trading, but far drawdown was limited to 12 percent ( that I've seen). I may place this on MT4 in which I will track performance using a system analysis EA.
Live account is up 68% since Dec 8, using a tiny open position at a slight profit. (trading EURUSD - USDCHF, and EURJPY - CHFJPY on Oanda).
