RSI does not observe higher values for period correctly

[markusmaresch]

Try a higher value for period - everything will be more or less neutral 50.0 - which is not intended/correct
Guess: delta = ohlc["close"].diff() .. needs to observe period correctly

RSI does not observe higher values for period correctly
The delta calculation in RSI should observe larger values for period
delta calculation should observe period: delta = ohlc["close"].diff(periods=period)
Always, conceptual
Latest, any
Try setting period to 1400 .. result will be +/- 50 (=neutral), which is not intended/correct IMHO
