Post From: sim (becktest) vs. live real time

it is not my code, it is your code that i tried to auto-backtest on different systems and on different sim account within the same copy of sierra to see how it behaves. what i found out was that it behaves slightly differently each time.

if your code does it, then mine will do it too for sure. why? because: (1) i am not a fulltime expert c++ senior engineer (i wish i were) and (2) i often use some parts of your code given as examples to build upon.

yes, you might say that the differences are slight and insignificant. i agree (sort of). when an entry timestamps differs in couple of dozens of milliseconds it is "insignificat" for some people, for others it is not, because different timestamp of an entry also means different price of an entry and it implies different price of and exit which may completely mess up all the rest.

again, i understand it behaves differently in live and sim. but i expected sim1, sim2, sim3 to be exactly the same for the same dll with the same setting (and it is your dll, not mine).

dont get me wrong -i am not accusing you of anything. i mean i really admire and appreciate what you did. i understand it must be extremely difficult to create something like a trading platform of this kind, with all its features, functions, support etc. - you are all heroes to me, no joke.

but please donĀ“t make a fool of me telling me that i should investigate my code and find out a why it is ustable - when it is your code given as an example
