MT4 script help

Im trying to set up a script telling me when stochastic goes over r lower a lmit.
i compiled it, no problem,
But when I apply to the graph, nothing happens....
any suggestion ?
Thanks

while(k<n)
{
StochCurrent = iStochastic(NULL,0,5,3,3,55,0,55,0);

if(StochCurrent>68)
{
Print("stochastic > 68!!! - SELL ");
return(0);
}

if(StochCurrent<35)
{
Print("stochastic < 35!!! - BUY ");
return(0);
}


}

I think the print function will print the message to your "journal tab" you won't see anything on the chart

A script is not the proper way to do this. It is for one time tasks such as downloading history or cancelling orders.

This code belongs in an indicator or perhaps an EA which runs continuously and does the computations for every tick. Also you should be using Alert() instead of Print().
