Hello, people. Has anyone encountered problems with the genetic algorithm? We optimise by genetic algorithm and get the result..... we choose the best one and look at the figure. Then we optimize again on the same interval with the same limits and we get a completely different result.... What is the problem, tell me......

Was the terminal disconnected from the internet between optimizations?
Hello, people. Has anyone encountered problems with the genetic algorithm? We optimise by genetic algorithm and get the result..... we choose the best one and look at the figure. Then once again we optimize on the same interval with the same limits and get a completely different result.... What is the matter, tell me......
This method of work gen. algorithm.
Do not use, or use it to define approximate settings. (so I understand there are a lot of variables to optimise.)
----- Was the terminal disconnected from the internet between optimisations?
Yes....Optimisation at all on a computer with no internet access...
I'm thinking about NormalizeDouble everywhere

I sometimes get different test results because I use my function instead of a slip,
which returns a random number of seconds of delay within the limits I set.
People, please advise! How do I make a position open and close on the expiry of a candle or candlesticks? That is, it opens at the opening of a new candlestick, and closes
How do I take the indicator values at the close of a candlestick?
I'm sorry, I can't figure out my "advisor", it chronically gives an error 130 wrong stops, and does not trade. I've set different stops, 10-60 pips, all the same.

Right after the start command I check if I have any open orders, and if I do, I exit the start with return; the corresponding strings look like this
int total=OrdersTotal(); Comment(" total ",total); Alert (" total ",total);
if ( total !=0 ){return;}
I think it should work, because my EA does not work properly; total is always 0, alternating with error 130.
Lots, TakeProfit and Stoploss are set accordingly, extern double Lots=0.1, TakeProfit=50, stoploss=10;
I don't understand what's wrong.
Help!!!!!!!!!!!! Please!!!!!!!!!!!!

My question may be simple, although I'm trying to do it myself, but my programming experience is close to 0. At least send me an example of some TS, which works according to this principle.
like this
static int KolBars; // this variable stores the number of bars
if ( your condition && Bars != KolBars)
{ // if the number of bars has changed on the screen - opening of a new candle is the condition for taking action
Actions according to the algorithm are done, closing position opening, calculations etc;
KolBars=Bars ; // record the number of bars at which the actions are completed
}
