Added topic TickData and the fxt-Files - change of policy?
Hi, while backtesting and optimizing I realized that something must have changed the way mt4 uses/handles the fxt-file - am I right? I have created the fxt-file myself (Birt's script) and first I launched the mt4 by Tickstory Lite and I get what you

Added topic OnTester() and TesterStatistics()
Hi, it seems that TesterStatistics() is working now (b628). While e.g. STAT_RECOVERY_FACTOR give a correct value the STAT_SHARPE_RATIO seems to be always 0.00000000 double OnTester () { //--- Print (

Added topic The Strategy-Tester - has it become a lot slower after b509?
Hi, unfortunately it is only a feeling but the optimization of my EA took 24 hours with b509 (as far as I remember) but now - same logic and same amount of vars with the same range to optimize ok the trade-vars are now organized by structs (one

Added topic really really mysterious??
At the moment only one terminal b625 is running, 4 charts are open and no EA is applied!! Now I started my script in debug-mode: line by line. It shall start my test_EA to check how I can set and get the chart comment - an all of a sudden I there was

Added topic the new Data Types are very annoying!!
The easiest way for an EA to get information either from another chart or from the previous start was to use GlobalVariables. But they only exists and can take and provide doulbes: 8 byte. If you now want to save a long (int) 8 byte too variable its
