You're talking about having a script or something to facilitate as a server for the EAs to be able to communicate. I think it'll take a while for metaquotes to come up with something like that. However looking at mql4.com, they say the function I was talking about, GlobalVariableSetOnCondition() is atomic in execution. With that, I can probably come up with a set of functions to do what I need.
Can someone help me: https://www.mql5.com/en/forum/174184 ?

need help - adjusted MACD
I am trying to create an indicator that adjusts the signal line based on the value of RSI. Really I would like to draw another signal line on the MACD that is adjusted and leave the regular signal line in place.
edit:
I got the indicator to draw the RSI line (first step) in the same window. But for some reason it won't draw the last period. Please see attached.
anythelp would be great

i changed the value of .0005 of the indicator in the expert as that only shows the channel line ultimately the levels are what you need to change 25,-25 for .0005 ...30,,-30 for .0006, and so on...
Problem with breakeven and trailing stop
Hello,
I am learning coding using the MQL4 tutorial from Codersguru, and I'm working on "My_First_EA". It really is my first EA. It works very well, but I am trying to write a breakeven stop and I can't figure it out. The problem I have is that the breakeven stop follows the price just like a trailing stop. I would like the initial stoploss to move to keep 1 pip profit when I make 15 pips (for example), then I want the stoploss to stay at the breakeven stop (1 pip profit) until the trailing stop begins working at 25 pips profit. Then I want the trailing stop to work as usual moving every pip of profit. I think the problem might be the "OrderStopLoss()", but I don't know anything anymore. My brain is mush. Thankyou
Here is the relevent code I've done:
extern double TrailingStop=25.0;
extern double BreakEvenProfit=15;
extern double BreakEvenStop=1;
......................
my entry and open orders code here works fine
......................
for (cnt=0;cnt<total;cnt++)
{
OrderSelect(cnt,SELECT_BY_POS,MODE_TRADES);
if (OrderType()<=OP_SELL&&OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUY)//Long position is opened
{
//should it be closed?
if (FSAR > FMA) //my exit signal
{
//----CLOSE LONG POSITION works fine
OrderClose(OrderTicket(),OrderLots(),Bid,3,Magenta);
return(0);//exit
}
////////////////////THIS IS THE PROBLEM AREA BELOW/////////
//----CHECK FOR BREAKEVEN STOP LONG POSITION------
if (Bid-OrderOpenPrice() > BreakEvenProfit*Point)
{
if (OrderStopLoss() < OrderOpenPrice()+ BreakEvenStop*Point)
{
OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice() + BreakEvenStop*Point,OrderTakeProfit(),0,Yellow);
return(0);
}
}
//-----EVERYTHING BELOW HERE WORKS AS A TYPICAL TRAILING STOP
//----check for trailing stop LONG POSITION
if(TrailingStop>0){
if (Bid-OrderOpenPrice()>Point*TrailingStop)
{
if (OrderStopLoss()<Bid-Point*TrailingStop)
{
OrderModify(OrderTicket(),OrderOpenPrice(),Bid-Point*TrailingStop,OrderTakeProfit(),0,Yellow);
return(0);
}
}
}
}
else//go to short position
