Explosive acceleration
A 0–10 score that adds up recent upward momentum, volume surge and up-bar count; 7 or higher is rare.
ExplosiveAcceleration adds three checks into one whole number from 0 to 10. Acceleration scores up to 4 points when the price change over the last fast_window bars is positive and more than 1.3 times the longer window's average pace over the same span, and 2 points when both windows are positive. Volume scores up to 3 points by comparing average volume over the fast window with the slow-window average: 2 points above the threshold, 3 points above 1.5 times it. Trend scores up to 3 points by counting up-closes in the fast window: 3 for at least 4, 1 for exactly 3.
How to read it
- The score sits in its own pane below the price, a whole number from 0 to 10, with no value for the first slow_window bars (20 at defaults).
- The median bar scores 2 at defaults. 0 means none of the three checks passed; 7 or more is rare, at the 95th percentile at defaults.
- Any score of 7 or more needs the last fast_window bars to have risen; without that the maximum is 6.
- Volume points fire on down bars too, so a rising score can come from a sell-off on heavy volume; check the candles before reading it as a move up.
What it outputs
- Explosive score
- Whole-number sum of the acceleration, volume and trend checks, from 0 (none passed) to 10 (all three at top points).
Settings
- fast_window
- Bars in the short look-back for price change, recent volume and up-bar count. Under 3 removes the trend points. Longer makes the 4-up test pass on most bars, so trend points stop telling bars apart. Above slow_window, volume points stop firing at defaults.
- slow_window
- Bars in the long look-back that sets the average pace the short move is measured against, and the volume baseline. Raising it steadies the baseline but delays the first value; lowering it makes the baseline jumpier. The first value needs this many bars.
- vol_threshold
- Volume multiple for the volume check: recent average volume above this times the slow-window average scores 2, and above 1.5 times it scores 3. Raising it makes volume points rarer. At zero or below, it adds 3 points on almost every bar.
Pitfalls
- A rebound from a drop scores like a breakout: if the longer window fell and the last few bars rose, the acceleration test still gives its full 4 points.
- Trend counts up-closes in the window, not a run. A random up-and-down market passes the 4-up test about 83% of the time at 10 bars, so trend points are common at long windows.
- Nothing here validates a high score against what followed. The facts show its distribution only, so treat 7 or more as a prompt to look, not a signal.
