I observed that there are two settings for “Color of Short Up” I would surmise that one of the settings should be “Color of Short Down” - most likely the bright red 255;0;0.
Your thoughts please.

THANK YOU CREATINGI THIS INDICATOR
ONE MORE REQUEST TO MODIFY THIS INDICATOR
1.CAN YOU EXTEND THE LINE TO CURRENCY PAIRS . IF IT IS LOOKING LIKE ALL CURRENCY PAIR GRAB LIST INDICATOR IT WILL LOOK BETTER.
2.CAN YOU HIGH LIGHT THE CURRENCY PAIR WITH GREEN WHEN SELECTED TIME FRAME ARE IN UP TREND{ AND } HIGHLIGHT IT WITH RED WHEN ALL TIME FRAME SELECTED IN LIST ARE IN DOWN TREND
ALL CURRENCY PAIR GRAB INDICATOR IS FOUND IN FOLLOWING PAGE

Your request is added to the development list.
In the meantime, try update version. This will fix, presentation, if a small number of time frames is used.
