forge.ta.rsi(source: ArrayLike,period: int = 14,method: str = 'wilder') -> np.ndarrayRelative strength index from average gains against average losses, 0 to 100.
Parameters
| Name | Type | Default |
|---|---|---|
| source | ArrayLike | |
| period | int | 14 |
| method | str | 'wilder' |
Indicator: Relative strength index
wilder smooths gains and losses with Wilder's average, seeded with the mean of the first
period changes (TA-Lib and MetaTrader 5). cutler uses simple averages. A window with no
gain and no loss reads 50. The first value is on bar period.
forge.ta.RSI(**inputs: Any) -> NoneMomentum bounded 0 to 100, from average gains against average losses.
Inputs
| Name | Type | Default | Range |
|---|---|---|---|
| source | source | close | |
| period | int | 14 | 1 to 5000 |
| method | choice | wilder |
gain = the change when it is positive, loss = minus the change when it is negative
wilder: the averages start as the mean of the first period gains and losses, then average = (previous average * (period - 1) + value) / period
cutler: the averages are simple means of the last period gains and losses
RSI = 100 * AvgGain / (AvgGain + AvgLoss)
A window with no gain and no loss reads 50.
