How to Put Object VLINE Under Candle To See the Upper/Lower Shadow of the Candlestick?
I want to make Vertical Line under the candle to see clearly the shadow/tail of candles or Is there any way to avoid hitting the candlestick?
There should be one—and preferably only one—obvious way to do it. (Zen of Python)
ObjectSetInteger OBJPROP_BACK is the one almost obvious way to do it.
If you don't need a vertical line, you could use an arrow and anchor it off the high/low.
You could draw 2 vertical trend lines above /below the high/low.
