I'm curious as to whether any of you that have used multiple different trading platforms, have ever tried using the same logic in the crafting of an automated strategy amongst more than one (better yet, *all*) of them, to determine how closely the results match between them?
I'm anxious to know whether there are little oddities built into any of them, or all of them, that cause minor differences. . . furthermore, if a few of them matched almost perfectly, but there was just one oddball that didn't line up with the others, this would seem to be fairly damning proof against the validity of the oddball platform. . .
I'm specifically thinking of Ninja, TS, Matlab, etc, the more mainstream platforms. . but any info in this regard would be very interesting and helpful.
