so it should check if there are no open positions with this wizard at all, no matter with what time of opening..... a simple limit on the wizard....toast

if(ExistPositions(NULL,-1,44444,-1)==false)//if there are no open positions with this magic number then check......

.... or maybe I do not understand.... I have -1 because I do not care when a position opened ..... anyway it will open only on a new bar and when the old one is closed because the conditions specify that the position can open only if there are no open positions with this magic number

to make it even simpler: open position and wait until it closes.... when it closes then opens again and certainly should not open on every bar a position with such a magician.... it is checked again if there are no open positions with such magician


So put 0 in the last parameter, so that it doesn't matter when the position is opened.

So put 0, in the last parameter, so it won' t matter when the position opened.

I did that and it didn't help, it still generates a position on every bar
gince:

if(!ExistPositions(Symbol(),-1,44444))OpenPosition(Symbol(),OP_BUY,0.1,Ask-sl*Point,Ask+tp*Point,44444)

it doesn't work either, still stamping a trade on every bar
Zver4991:

it does not help still stamping on every bar

found the mistake..... it is all about the symbol I was setting that I do not care what symbol to look for as long as it would not be with this magician but when I set that the current one is ok to start....though strange because if it is not on the current symbol and is on another then we would not have to open the deal until it closes on the other symbol with this magician

How can I introduce a parameter such as the angle of a moving average with certain parameters into an EA?
How can I prevent the limit from being set if it's already set?

It depends on what to prick )))

compare by price, if at this price +/- a given spread there is already a limit, do not put a new one
