{quote} Hi abowaik, Thanks for sharing your code. I hope this is not out of place, but here are a couple of tips... A necessary step in working with multiple symbols is to first ensure that the symbol is selected in the market watch window. Since the SymbolSelect function will return false if the symbol does not exist, I would recommend replacing your invalid_pair function with if(!SymbolSelect(pairs,true)) { Alert("Error : Invalid Pair : "+pairs+"\nCheck Symbol Settings"); return(INIT_FAILED); } Or even better yet use CSymbolInfo which already...

{quote} You can use custom symbols inside backtester. And custom symbols are old offline charts in mt4. Then its evident you dont have any idea about MT5. MT4 will die soon because brokers will kill it. 1/4 price fee, new broker tools, dealer out of box...

{quote} Thanks, I didn't know that. I have just created my first custom symbol in MT5 and I'm in the process of importing HST files from my live MT4 account. Have you done it and are you happy with the quality of the data?

Hi guys I’ve replaced my loved MT4 by MT5 since December last year. I think MT5 is the logically next step and the development in MQL5 is much easier than in MQL4. Well guys, I’ve only one big problem with MT5. My MT5 is eating so much cpu that it is sometimes impossible to start a trade. I’m running v5 build 1755 (newest one). I’m a manual trader and haven’t running a automatic trader (EA). The only thing what I’ve running is a toolbox as expert for all my manual trader stuff eg fibos, buy sell Buttons etc. The toolbox is just a panel with some...

thank you for u'r reply. {quote} Yes, I've more than 500 synthetic symbols, but they are all disabled because atm they are not in use. I've build a bridge for the cryptocurrency market. My bridge is loading all OHLC data from binance into MT5 - so that I can analyze them in MT5 (much easier than in the shitty binance chart :-)). But this bridge is atm not active because I've no free time for the crypto market. {quote} Well, I can't share the complete code, but probably you're right.

{quote} You should run the profiler to find out which element in your code is leaching CPU, if any. Also you could easily implement the CObject Load/Save virtual methods by adding your objects to CList or CArrayObj which will serialize and save/load them to/from a bin file. Here is some example code. https://github.com/nicholishen/Chart...ileManagerMql4
