The owner of the nameless "robot" in question demurred:
Not a martingale system is all I can say
What shall I say when seems some of you have all the answers looking to a simple chart?
so I pointed out:
The "simple equity curve" speaks for itself Peter!
Peter demurred some more, so eventually I conceded:
In the absence of credible evidence to the contrary I'll stick with "Martingale like money management".
All of this prompted me to bring Ray the Random Robot back from the dead! A quick test suggested that even the very latest incarnation of OOP enabled MetaTrader 4 still doesn't allow backtesting of multiple instrument strategies. A rummage around my hard drive revealed that version 8.80 of the ActivTrades flavour of MetaTrader 5 was all present and correct. I fired that up, opened a new demo account, and it wasn't long before Ray was happily playing with pretend money in MetaTrader land once again. I let him loose on a basket of USD crosses starting arbitrarily on January 1st 2016, and this was the pleasing result:
Evidently there's life in the old donkey's head yet!

Regular readers may recall that Ray Robot Senior uses (pseudo) random entries with a 50 pip profit target and stop loss. Without even bothering with "optimisation" and the like he somehow managed to produce a total net profit of $548,578 over the course of somewhat less than 14 months. Ray assures me that works out to be well over $20,000/month profit. In Monopoly money of course!
The question therefore remains:
What has Peter's Paragon system got that Ray the Random Robot does not?
The inverse question is easier to answer. Peter's robot doesn't come complete with full source code.
[Edit - February 26th 2017]
I've upgraded my copy of MetaTrader 5 to build 1545. The Strategy Tester now has a "Every tick based on real ticks" option, which I don't recall seeing before.
I tried testing Ray again using that, but it seems to have a bug:
Perhaps it's confined to USD/JPY? I think I'll try testing Ray Robot Jr. with "real ticks", too see if MT5 now gets closer to duplicating his real money trades than it used to!
