c_rsi_14d_dividend_and_split_adjusted(m_close_dividend_and_split_adjusted)[source]

Calculate the 14-day relative strength index (RSI) for dividend-and-split-adjusted close prices.

Parameters:

m_close_dividend_and_split_adjusted (DataColumn) – The adjusted close prices.

Returns:

The 14-day relative strength index.

Return type:

DataColumn

Notes

The RSI is computed as:

\[\mathrm{RSI}_{14} = 100 - \frac{100}{1 + \dfrac{\mathrm{Average\ Gain}}{\mathrm{Average\ Loss}}}\]

In Excel, assuming your adjusted close prices are in column A starting at cell A2:

  1. In cell B3, enter:

    =MAX(A3 - A2, 0)
    

    and drag down to compute daily gains.

  2. In cell C3, enter:

    =MAX(A2 - A3, 0)
    

    and drag down to compute daily losses.

  3. In cell D16, enter:

    =AVERAGE(B3:B16)
    

    to compute the 14-day average gain.

  4. In cell E16, enter:

    =AVERAGE(C3:C16)
    

    to compute the 14-day average loss.

  5. In cell F16, enter:

    =100 - (100 / (1 + (D16 / E16)))
    

    to compute the 14-day RSI.
