Crypto Tripple RSI

Gives an ability to compare 3 RSIs:

• current altcoin + BTC (e.g. ADABTC) - green by default
  
• current pair (e.g. ADAUSDT) - blue by default
  
• BTC (e.g. BTCUSDT) - yellow by default
  

It helps to understand the cause of price change - whether BTC provokes price change or not. Also it shows performance of an altcoin - the bigger gaps between RSIs, the stronger (RSI of BTC is on the bottom)/ weaker (RSI of BTC is on the top) altcoin is.

Versionsinformation:

Just moved `transp` argument (obsolete soon) into `color.new`

Versionsinformation:

• Add important levels (explanation link in the code)
  
• Add alerts
  
• Add markers, when X RSI crosses up or down BTC RSI
  

Versionsinformation:

Some cryptocurrencies has no pair with BTC which caused errors. I have added ability to choose second and third source of RSIs (formerly BTC RSI and X_BTC RSI). Besides the third RSI is hidden by default because there is no way to dynamically set third source in settings. But now it is universal and you can use it not only with cryptocurrencies :)

Versionsinformation:

• New levels: 80 and 20
  
• Additional lines: 75 and 25
  
• Ability to change resolution of #2 and #3 RSI
  
• Separate source and length for all RSIs
  

Versionsinformation:

• New RSI: "Additional current RSI" - to compare current RSI with different timeframe
