||The Intraday Momentum Index (IMI) is the same formula as the Relative Strength Index (RSI), except intraday differences are used as input. In otherwords, while the RSI uses the day-to-day change as input, the IMI uses the difference between the high and low values for the day. The IMI was designed by Tushar Chande.
The only parameter used with the IMI on StockFetcher is the period. The period is used within the RSI-based formula. Additionally, the results from the IMI measure are scaled between 0 and 100.
