too bad, right. (had settings log file at "0 days" and closing/re-opening mfp deleted them..)
the logs for the trigger responsible for the betting was 100% ok in these cases where the back-2:2 was not placed, I checked them accuratly. the end was always in green letters "going to back on..." after all conditions were true.
the trigger for the program I did NOT checked..
now I remember that: when I noticed the missing bets, I placed the bets manually and at the first of them I had the mfp-sound of error every time when I pressed the price-button to place a bet, for 10-15 seconds. but then no more.
conclusion: I dont want to request all the attention here. it has no sense, I think, if I dont have the logs. I will notice this strange-thing the next 7 days and in case that it happens again, I will make screenshots of all logs.
till here thank you very much.
