The RSI is awesome, but the Chande Momentum Oscillator is awesomer!!! The Chande Momentum Oscillator (CMO) is a technical analysis indicator created by Tushar Chande that measures pure momentum in a security’s price, oscillating between +100 and -100.
It’s similar in spirit to RSI, but instead of comparing average gains and losses, it adds up all price changes (up and down) over a period and divides the net change by the total absolute changes — giving a percentage measure of net momentum.
In the chart below of TSLA, I have marked areas in the dashed lines of an aggressive entry/exit and solid lines a more conservative entry/exit examples using the supply and demand zones as final criterias

Script for this indicator can found below
mod note:
Oscillator Formula
For a chosen period n:
CMO=100×Sum of Gains over n−Sum of Losses
Where the formula calculates the Sum of Gains = sum of all positive price changes during n and divides by the Sum of Losses = sum of absolute values of all negative price changes during n.
Key Characteristics
-100 = extreme downward momentum (all periods were down)
0 = equal gains and losses over the period
Below -50 → strong bearish momentum
Crosses above 0 → momentum turning bullish
Crosses below 0 → momentum turning bearish
-50 to -100 can be oversold
But thresholds can be adjusted depending on volatility.
How I use it to trade:

Key Characteristics
- Bounded Range:
-100 = extreme downward momentum (all periods were down)
0 = equal gains and losses over the period
- Faster than RSI:
- Interpretation Zones:
Below -50 → strong bearish momentum
Crosses above 0 → momentum turning bullish
Crosses below 0 → momentum turning bearish
- Overbought/Oversold:
-50 to -100 can be oversold
But thresholds can be adjusted depending on volatility.
How I use it to trade:
- Trend Confirmation: If CMO is above zero during an uptrend, momentum is aligned.
- Overbought/Oversold Reversals: Look for extreme readings followed by a cross back toward zero.
- Divergence: When price makes new highs/lows but CMO fails to confirm.
