Help to fix this formula

[Barros]

Most of the time the last 3 or 4 bars appear in white.
Please, can someone help me to fix it?

That is happening because you have not defined a default color for the price bars. You have two ways in which you can correct this.
For the first one open the efs with the Editor and add setDefaultPriceBarColor(Color.black) in preMain (or use any color of your choice).
If instead you would like to be able to define a default price bar color from within the Formula Wizard then you need to add a Set (this should always be the last one) in which you write a condition that is always true by definition such as for example 1==1. Then in "the following will happen every time" set the color of the price bar to your desired default color
