    The Intraday Momentum Index (IMI) indicator is a version of Relative Strength Index (RSI) that considers the relationship between a security's Open and Close prices instead of difference between the close and previous close, which is used in RSI. The IMI's line can help identify when a security is overbought (the line is above 70) or oversold (the line is below 30).

    IMI = 100 * (UpDaysSum / (UpDaysSum + DownDaysSum))

    UpDaysSum &nash; the sum of gains on up days  for the period (CP - OP)
    DownDaysSum – the sum of losses on down days for the period (OP - CP)
    OP – open price
    CP – close price
