Is this true for everyone else or did I mess up my mt5 by connecting to other brokers?

Nothing to do with connecting to other brokers. What is 'mql demo server' ? Metaquotes demo server ?

Please show your code.

it was working fine for a year then stopped working on gold. For instance, this works on all majors but not gold:

request.price=NormalizeDouble(CalcHigh-step+spread+cushion,_Digits);

for gold only this works:

request.price=NormalizeDouble(CalcHigh-step+spread+cushion,2);

in gold, _Digits is 3 but either of these gives invalid price:

request.price=NormalizeDouble(CalcHigh-step+spread+cushion,_Digits);

request.price=NormalizeDouble(CalcHigh-step+spread+cushion,3);

invalide lotsize error invalid stops / avoitenko What's wrong with using

Anyway your price is not well normalized. It only works if a point (digits) is the same as ticksize.

You should use ticksize to normalize your price.

it seems to be a bug in mt5 newest build, I shall report it.

Is it worth to answer you ? There is no bug in MT5, it's a bug in your code.

No worries. It can happen.

I suppose something like:

SymTicSize=SymbolInfoDouble(_Symbol,SYMBOL_TRADE_TICK_SIZE);
priceinticks=NormalizeDouble(notnormalprice/SymTicSize,0);
normalprice=priceinticks*SymTicSize;
