Dominance Pie Chart

A different type of charting, the pie chart,
here for showing the available dominance on one chart,
together with the total % dominance per ticker and between brackets
the % rise/fall.

Can be used in every timeframe

(It is normal it takes some time to be loaded)

Cheers!

Notes de version:

- Added the feature 'ignore_invalid_symbol' https://www.tradingview.com/pine-script-reference/v5/#fun_request{dot}security (with much thanks to Tradingview/Pinecoders!)

In the past, the script gave an error when a ticker wasn't available.
Now, when this happens (because of 'ignore_invalid_symbol') the script's execution continues
with the unavailable ticker giving 0.

- Converted to Pinescript v5
