EA draws MA

How can I draw MA line from my EA?

Thank you in advance

If you want to draw a moving average line with your EA, you need to obtain the moving average value from the indicator function, then paint it onto the chart using the trend line option with the ObjectCreate() function.

Here is an example to draw the moving average trend line.

This code is executed at the close of each bar.

static double MA;

static double previousMA;

previousMA = MA;

MA=iMA(NULL,0,20,0,MODE_SMA,PRICE_CLOSE,0);

int time2=Time[0];

ObjectDelete("Tr1"+time2);

ObjectCreate("Tr1"+time2, OBJ_TREND,0,Time[0],MA,

Time[1],previousMA);

ObjectSet("Tr1"+time2, OBJPROP_COLOR,SteelBlue);

ObjectSet("Tr1"+time2, OBJPROP_RAY,false);

ObjectSet("Tr1"+time2, OBJPROP_STYLE,STYLE_SOLID);

templates

Hello,

1- There's no sounds for SL/TP events in MetaTrader.

2- You can save all the indicators and the objects of a chart to a template then reload it when you need:

Right click the chart you want to save it as a template.

Choose Templates -> Save Template ..

Give it a name and save it.

To Load the template you saved:

Right click the chart you want to load the template on.

Choose Templates -> Load Template ..

Choose the template.

Reversing Trades MQL

Hey,

I'm wondering if there is any simple way to reverse the trades an EA makes. I know a decent amount of MQL, but I'm not sure if there's an easier way to simply turn all buys into sells and sells into buys, reversing the logic of the trades other than editing every piece of logic. Is there any easier way of doing this?

Thanks

OrderSend Function

You will not need to change every piece of code.

Just OrderSend function you need to replace:

OP_BUY to OP_SELL and OP_SELL to OP_BUY

Ask to Bid and Bid to Ask

and of course change the stoploss and takeprofit in the OrderSend function.

Depending on how the EA is coded it might be even simpler than CG's solution.

If the EA calls functions to send the orders you could just change the calls.

For example..

Instead of

if(Signal()=="BUY")OpenBuy();

You would just change the call to the OpenSell function instead.

Hope that helps.
