I have been trying to figure out how to color the chart background based on historical signals (in other words as a buy signal is generated the background changes to light green etc) but I am stuck as whenever the newest signal is generated it colors the whole background based on the latest signal overriding the historical signals coloring of the chart. I have looked into the GFX functions which I am guessing I have to use to do this but I am in over my head at the moment. Any pointers would be most appreciated.
Thanks DM
