Thanks

It shouldn't be changed.

If you close partial lots then yes a new ticket number is generated, if you only update stops then the tikcer number will not change.

What does this mean?? It relates to placing a trade with the EA.

It means bad stop price. In orderSend, the stop is a price and must be at least 10 pips below the entry price for buy or 10 pips above the entry price for sell

Hi,

Error table error for MQL4: Error codes - MQL4 Documentation

ERR_INVALID_STOPS130Invalid stops.

Thanks! I am testing with several modifications/additions to my EA now. It worked with North Finance and Interbankfx, but did not work with the new brokerage firm that North Finance is promoting now - FXpro.com. They have some great features and are faster and are Euro regulated, and they went to a fifth decimal place on some currencies. I suspect Fxpro's MT4 platform has had modifications to it to support the additional decimal place, consequently as I transferred over my reliable EA's to their platform, they no longer would work. The error 130 was what I was getting.

I give up with FXPro's demo accounts. No matter what I do to enhance or fix the stoploss in my EA that works perfectly on other brokerage firms platform - It still gives me the same #130 error. I give up!!

Hi

I'd like to know how to build my own moving average with the average of 4 indicators.

double ma = iMA(NULL, 0, 14, 0, MODE_EMA, PRICE_CLOSE,Current + 0);
double ma_m15 = iMA(NULL, PERIOD_M15, 14, 0, MODE_EMA,PRICE_CLOSE, Current + 0);
double ma_m30 = iMA(NULL, PERIOD_M30, 14, 0, MODE_EMA,PRICE_CLOSE, Current + 0);
double ma_m60 = iMA(NULL, PERIOD_H1, 14, 0, MODE_EMA,PRICE_CLOSE, Current + 0);

double var1 = ma , var2 = ma_m15 , var3 = ma_m30 , var4=ma_m60 ;

double var_myMA = (var1 + var2 + var3 + var4)/4;

How can I draw var_myMA in the main window? I don't know how to use ObjectCreate()

Best regards

Hi,

Take a look at this thread. You also could use the Moving Average indcaitor code as example, or the MACD code and so on.

Quote:

SetIndexStyle(0,DRAW_LINE);
SetIndexBuffer(0,var_myMA);
