Import Forex Volume from 5 biggest FX Brokers (single/combined)

Some Brokers like Forex.com don't show Volume for FX. This indicator allows user to import Volume from a range of FX brokers that DO show volume

-Combine the reported volumes from all five brokers: FXCM, GLOBALPRIME, PEPPERSTONE, Currency.com, OANDA. Or pick a specific broker to import volume from.
-Image above shows combined Volume from the big 5 brokers, with added notes on the 2yr average of various broker's volumes; showing their size in descending order.
-Works across timeframes & FX pairs. Standard color formatting options Added.

//notes:
~default settings pull/combine volume from all 5 brokers. History goes back to Sept 2019 (due to GlobalPrime's later start date in publishing Volume data).
~~toggle ON 'only show FXCM, Pepperstone & Oanda' for a LONGER history, going back to June 2012.
~individual broker feeds: top checkbox toggled OFF, choose your preferred broker.
~~FXCM has both the longest history and the highest volume size of all the brokers.
~Table (toggle on/off) shows the broker feed (which broker(s) volume is on display) and the SMA 100 to give an idea of relative size.

//Cautionary note:
Volume is not as reliable in Forex as it is in Equities/commodities, due to unreported Inter-bank trades; the broker volumes do not give the full picture, but this is a best approximation of combined total volume based on brokers reported volume. The true volume will likely be much higher.

-Thank you @theEccentricTrader for the idea of pulling volume feed from other brokers.
