I'm working with Indie script to create a candlestick pattern indicator, and I'm facing an issue with how labels are displayed on the chart. As you can see in the attached screenshot, the candlesticks are currently rendered on top of my pattern labels.
What I need help with:
Label Order: Is there a way to make the labels appear in front of the candlesticks instead of behind them? Currently, the candlesticks are obscuring the labels, making some of them difficult to see.
Label Transparency: Is it possible to make these labels semi-transparent so that even when they're in front of candlesticks, the underlying price action is still somewhat visible?
Here's the relevant part of my code for the label markers:
@plot.marker(color=color.GREEN, text='BE', style=plot.marker_style.LABEL, position=plot.marker_position.BELOW) # Bullish Engulfing
@plot.marker(color=color.TEAL, text='MORN', style=plot.marker_style.LABEL, position=plot.marker_position.BELOW) # Morning Star
I've searched through the TakeProfit/Indie documentation but couldn't find options for:
Controlling the z-index/order of elements on the chart
Setting transparency for markers/labels
Any alternative ways to highlight patterns that would solve this visibility issue
