Ok, for the next version if it’s not already add, you need to add : -STOP button for the « strategy optimizer » -And a pop up box with an advertisement of the RAM utilisation with this process. Bec it’s use 100% of the available RAM / Proc and maybe can make trouble for the bot with calculation of trade -Add an export button for the results Bec if the user launch another test, the new test will overwrite the old results And make a save on the server can outofspace really quick the VPS storage => why not a function with If the user save the log it’s increment by 1 a register If it’s note save this same register was 0 And when the user click on the « start optimizer » the script will check if the old log was save « 1 or 0 » and if the register was set to « 0 » , he will open an advertisement box « Warning you’re trying to launch another simulation without saved the last test, if you want to continue this test will overwrite the old log. Are you sure ? Yes/No » And launch after ! this simple things can avoid mistake from non-vigilant user ( hope you understand all, I can write in French ^^ if my English not comprehensible )
