Place an arrow/object/image next to a Candlestick data point

Does anyone know if/how you can add an Arrow next to a Candlestick data point? So say for example you wanted to represent an entry/exit price within the candle.

Ideally it would be nice to have the ability to add a candle-facing arrow (from left or right side) at a specific price point.

Or maybe there’s an alternative. I suppose I could add text above the candle, but I think it could look more appealing if there was a symbol or graphic that you could add instead.

Have you looked at https://plot.ly/javascript/text-and-annotations/#simple-annotation ?
