trade only one time a day
GumRai,thank you very much.
I will have a try.
Try to see if this is useful
datetime midnight = TimeCurrent()-(TimeCurrent() % (PERIOD_D1*60)); for(int i =OrdersHistoryTotal( )-1 ;i>=0;i--) { OrderSelect(i, SELECT_BY_POS, MODE_HISTORY); if( OrderMagicNumber( ) ==MagicNumber ) { if ( OrderOpenTime()>= midnight) return(0); } }
Try to see if this is useful
It's not...
only the EA has to trade one time a day
it can't trade at all if some other trade is closed other Symbol() same MagicNumber( )
you can check this way only OrdersTotal after Start
before the EA has opened his first

I wouldn't have thought that anyone would usually have 2 EAs with the same magic number running at the same time, but who knows :)
I was in a bit of a hurry to go out when I posted before, corrected the mistake, but still forgot to include the scan of open trades.
Are you saying that this will not work at all?

Maybe it would be better to assign a value to a variable instead of return() ?
Then check the variable to see if any new trades could be opened.
That would still allow the EA to modify any open trade if necessary.

You can place EA on different, charts trading the Symbol of the attached chart only, in that case if you check also the Symbol then there is no need to have other magicnumber
After Start() you can do check every tick all the trades you had done on your account but you make your EA slow doing that...
It is simple to me to change the code that way that it does ordermodify the trades when it is needed i gave this as example for trading once a day
you can check my way it is not needed to check OrdersHistoryTotal() inside Start()

I will look through your code and will hopefully learn from it. :)
I think that you made a bit of a typo in init
for(int i= OrdersHistoryTotal()-1; i>=0 ; i--) //count down if you check trades !!! { if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false)break; if(OrderSymbol()!=Symbol() ||OrderMagicNumber()!= MagicNumber ||OrderType()>1) continue; if(OrderOpenTime() > bod) { opentimelastmarket = OrderOpenTime(); break; } }
you assign OrdersHistory total to int i, but then scan open orders.

thanks good point mode_history it has to be
will edit original code
deVries,
that is excellent. I see what you mean, that closed trades only have to be scanned in init.
Just a couple of points. If an OrderSelect fails, the code will exit the loop and will discontinue the checking.
I must admit, that I am pretty useless at error handling and often see in peoples code
if(OrderSelect() ) but usually this error is ignored and continues with the next order position. I really don't know what to do when OrderSelect() fails as I would be concerned that simply restarting the loop would repeat the failure and the program will be stuck.
That can't be good, but then again, exiting the loop or just using the data from the loop when OrderSelect() doesn't fail can't be particularly good either.
The other point
if(EATrades != OrdersTotal()) { BUYTrades = 0; SELLTrades = 0; EATrades = OrdersTotal(); //reset counting trades for(int i= OrdersTotal()-1; i>=0 ; i--) //count down if you check trades !!! { if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false)break; if(OrderSymbol()!=Symbol() ||OrderMagicNumber()!= MagicNumber ||OrderType()>1) continue; if(OrderOpenTime() > opentimelastmarket)opentimelastmarket = OrderOpenTime(); if(OrderType()==OP_BUY) { BUYTrades++; } if(OrderType()==OP_SELL) { SELLTrades++; } } }
Unlikely, I know, but it is possible that at the same time that the EA is opening a trade a different trade is being closed.
That would mean that at the next tick, EATrades would still == OrdersTotal(), so opentimelastmarket would not be updated and another trade will be opened.
Would it be a good idea to check that the OrderSend is successful and if it is, then update opentimelastmarket there?

I have written a breakthrough EA,after a month test,I found that sometimes it loses several times within a day.
Therefore,I want to revise my EA,to make it trade only one time a day.Could anyone show me how to realize that?Thanks
