Open Interest All Exchanges

The indicator collects data from available exchanges based on open interest. The indicators are calculated in the amount of Bitcoin.

Below are the tickers of the exchanges that provide the data:
- BITFINEX:BTCUSD
- BITFINEX:BTCUST
- KRAKEN:BTCUSDPERP
- BITMEX:XBTUSD
- BITMEX:XBTUSDT
- BINANCE:BTCUSDTPERP
- BINANCE:BTCUSDPERP (due to low volumes and limitations of 40 requests of the request.security function, the code contains data without using the calculation)

For me, Open Interest indicators play an important role in the trading system, for this reason I share with you. I am not a financial advisor.

**Open for cooperation**
