Indicator not drawing arrows

New comment
 

I have been trying to modify the stochastic histogram indicator so whenever a bar appears above 0 then an arrow will be drawn on the chart to buy. Then whenever a bar appears below 0 then an arrow will be drawn on the chart to sell.

However, the indicator will not drawn the arrows. Here is the code:

}

I'm sure I am missing a pretty basic part, so could someone please tell why the arrows are not being drawn?

Thank you for your time!

I think these lines need to be within the for loop . . .

if(upB[shift] <= 0) Arrow_Dn[shift] = High[shift];
   if(loB[shift] > 0) Arrow_Up[shift] = Low[shift];

Thanks for the reply I appreciate the help but it still is not drawing the arrows.

Here is the updated version:

}
 

You also need to set this . . . 

IndicatorBuffers(3);   //  <---  5 buffers not 3
 
Then look at the values in the Data Window and make your code do what you think it should be doing . . .

Yep that fixed it they are now drawing.

Thanks for the help!
