This script combines the "ticker volume" from 9 different exchanges. The default settings are for Crypto Assets only. In the settings window you can choose to plot the "combined volume" in a histogram form or "individual exchange volume" in an area view. (as shown on the chart) Addition to the plots there is also an Info Table in the bottom right corner that brakes down the volume to individual exchanges, shows how much volume was traded on which exchange. If the Table shows "NaN" on an exchange you need to check the spelling of that exchange, if thats correct, than the ticker is not available on that exchange.
Could you include crypto / stablecoin pair volumes like USDT and USDC into this indicator? Thanks.
