I just wanted to compare BTC volume from more than one exchange on the same chart.
So I spent 3hrs TOSSING OFF WITH GUIs then did it in Pine.
I don't like GUIs, especially when it takes me 3hrs to TOSS ONE OFF.
After this "new" indicator has saved, I will be able (I hope) to add symbols (e.g. Coinbase:BTCUSD) to my Bitfinex:BTCUSD chart. I will right-click the new symbol and add an indicator to it.. and my poncy, little Volume indicator will show up so I can overlay it on the new symbol. Right now it doesn't come up in the indicator options, even tho I have written and saved it.
I will repeat this with a bunch of exchanges on this one chart.. then put them on the same scale... then hide all the price charts...
and FINALLY be able to compare volume of exchanges properly in kinda real time.
