additional visualization option for BIG TRADES indicator

I would like to request an additional visualization setting for the Big Trades indicator.

Currently, users can customize the shape and color of the bubbles. However, because the bubbles are fully filled, they often overlap with the candles and make the chart look cluttered and harder to read.

My suggestion is to add a new display option:

• An “outline only” mode for the Big Trades bubbles

• In this mode, only the bubble’s border/contour is drawn, with no fill color inside

This would keep Big Trades visible, but make price candles and other chart elements much easier to see.

I have attached an image to illustrate what I mean.

Thank you for considering this improvement.
