Thank's agin in advance for any help in this.

s01 wrote:LOL, Guys,

Now totaly confused ...

I understand from the Empty4 documentation that the begin wants a number, but then in the sample it has text.... Copy/Paste from the Empty4 website

So I want a number there? Or not?
Very confusing in the documentation.
If I place a number there,min number of bars counted or some such,
then how do I recall to get the line drawn again?

extern int SignalSMA=9; //length of Signal moving average

That seems pretty convoluted. Why not just return(MathRound(dbl)); ? (Or MathFloor(), depending on what you want.) I'm pretty sure MQL will properly convert the double MathRound() return value to Integer, since the DoubleToInt return value is integer. If not, you could just assign MathRound(dbl) to an int and then return that.

NeoTrader wrote:you're right...you could also use the math functions...but they still produce doubles...and maybe mql converts them to int (I'm not that sure what mql does at some times).
In my solution ( as convoluted as it seems) I'm sure I have an int at the end.
