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!!

build my own moving average

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.

SetIndexStyle(0,DRAW_LINE);

SetIndexBuffer(0,var_myMA);

I highly recommend you to read this section: https://www.mql5.com/en/forum

Trade multiple currencies in one EA

Hi,

I just have a quick question. How do you trade multiple currencies with one EA so the statement has all of the currencies included. Right now I have to trade my EA on one currency at a time, and I want to see how the EA would perform on multiple currencies at the same time. This would make it a lot easer to see how the EA would perform on all currencies during a back test.

Thanks for your time!

You CAN trade multiple currencies with one EA. You CAN NOT back test multiple currencies using one EA in the back tester.

thanks MiniMe for ya prompt reply; heres i attach example of the ea...

see the private message please

it would be easier to post the whole code , as the one you post doesn't compile

here is my comments

1- first you need to check OrderIsOpen=0 or 1 before you enter the loop , i think that is done by calling Mytotal() at start then set OrderIsOpen to 0 if Mytotal==0 and set OrderIsOpen to 1 if Mytotal==1

2- you don't need to keep using return(0) in the main code that would terminate the code

3- I am not able to compile the code as its missing the main function but I guess if you take care of the above points you should be ok
