Rsi in Double data type !

[moslem7026]

i see that data type of rsi value has been changed to double , whats going on sma that has decimal point ?

Stock.Indicators/src/m-r/Rsi/Rsi.Models.cs

Line 11 in e64d14e

public double? Rsi { get; set; }

We've had a rather long prior conversation on using decimal vs. double. I'm sure there are a few inconsistencies in the library, but we prefer double for performance, but persist decimal for precision when appropriate.

The convention we use prefers double when the results are abstracted away from price to favor its relative computational performance. For example, RSI is on a 0-100 point scale with low or no benefit to decimalized precision, so double works fine. In price overlays or transforms, like SMA or Renko, we stuck with decimal to keep the price-domain usable for monetary calculations.

In version 2.0, we went further, to make all but pure price-based transforms results double. Currently, we're only using decimal outputs for more pure candle transforms like CandleProperties, Renko, Heikin-Ashi, etc. There may be a few exceptions.

If your question is "why isn't RSI an integer?", I'd say because it's not accurate enough as an integer, especially if re-used in chaining models. If you want it as an integer for your use case, you can convert it:

// example, make RSI an integer
var results = quotes
    .GetRsi(..)
    .Select(x => new { x.Date, Rsi = (int)x.Rsi });
