Summary: The funding rate is the interest charged / credited to a perpetual futures trader for taking a long or short position. The direction of the funding rate is used as an indicator of trader sentiment (+ve = bullish; -ve = bearish), and therefore useful to plot in real time.

The FTX exchange has published the calculation of their funding rate as follows:
TWAP((future - index) / index) / 24

The formula here is the same, but expresses it in the more common % per 8hr duration:
funding = TWAP((future / index) - 1) * (8 / 24) * 100

For reference: future refers to the FTX bitcoin futures contract price (FTX:BTCPERP) and index is the spot price of bitcoin on the exchange (FTX:BTCUSD)

Additional notes:

• Probably best to add to the indicator to a new pane, or as secondary axis
  
• Plot this in combination with FTX:BTCPERP or FTX:BTCUSD, or chart of your choice to complement your bitcoin dashboard
  
• Compare to funding rates published on ViewBase

Nota Keluaran

This is my official set of updates to the funding script. I hope it proves much more visually appealing, and useful. Updates:
- Used step plot to show that funding changes each hour
- Added a zero line for reference. You can actually add alert now for when zero-crossing occurs (use at own risk!)
- Default values updated for better accuracy; funding should now be viewed on hourly timeframe, with 1m/1hr resolution setting.

Nota Keluaran

2021-04-19 UPDATE: Now you can change ticker symbols to use with other exchanges. CAUTION(!): I HAVE NOT TESTED ANY OF THESE PAIRS FOR CORRECTNESS. Please also note that this will calculate funding using FTX's formula--so it's not guaranteed to be a "true" or even good measurement of the actual funding rate at your respective exchange. Please compare, and use your own discretion--this is just a jumping off point for your own creativity and analysis!

Add'l exchange pairs (exchange / perp symbol / spot symbol):
FTX / FTX:BTCPERP / FTX:BTCUSD
BINANCE / BINANCE:BTCUSDTPERP / BINANCE:BTCUSDT
OKEX / OKEX:BTCUSDTPERP / OKEX:BTCUSDT
HUOBI / HUOBI:BTCPERP / HUOBI:BTCUSDT (! This pair seems visibly *incorrect*)

Nota Keluaran

Added a tickbox to select between displaying a 1hr funding plot and/or an 8hr plot.

Nota Keluaran

Small fix to ensure that precision is set to 4 by default. Before, it had low precision and the values/axes just looked like zeros.
