Rate of Change Indicator [JopAlgo] (ROCI)
Rate of Change Indicator (ROCI) [JopAlgo] — see impulse early, skip the dead moves
What it is (one line):
ROCI tells you how fast price changed vs N bars ago, in percent. It’s a clean momentum gauge:
Above 0 → price is higher than N bars ago (bullish momentum).
Below 0 → price is lower than N bars ago (bearish momentum).
Further from 0 → stronger impulse.
The default +5 / −5 bands highlight strong thrust. Zero-line crosses flag momentum shifts.
What you’ll see
Blue line = ROCI.
Orange dotted line = 0 (bull/bear divider).
White dotted lines = ±Strong Momentum levels (default ±5).
Green/red panel tint when ROCI lives above +5 or below −5.
Read in 3 seconds: Which side of 0? How far? Growing or fading vs last bar?
How to use it (simple playbook)
Direction filter
Trade longs only while ROCI > 0.
Trade shorts only while ROCI < 0.
Timing
Breakouts: prefer breaks where ROCI pushes through +5/−5 and holds on the first retest.
Pullbacks in trend: in an uptrend, let ROCI dip toward 0 and then turn back up → entry. (Mirror for downtrends.)
Do less in chop
If ROCI whips around near 0, you’re in balance. Only act at objective levels.
Rule of thumb: Zero cross = heads-up. ±5 hold = go-with.
Entries, exits, risk (use this, keep it tight)
Continuation entry (trend):
Bias up at your level (e.g., VAL/AVWAP). ROCI stays > 0 and turns up from a shallow dip → enter long.
Stop: under structure/level. Targets: POC/HVNs or next swing.
Breakout entry:
Break through a level with ROCI > +5 (or < −5 for shorts). Enter on the retest that holds while ROCI remains outside the band.
Invalidation: quick fall back inside the band and under 0 → stand down.
Exit/trim:
On longs, repeated lower ROCI peaks into your target (momentum fading) → take profits or tighten.
Timeframe guide
1–5m (scalps): ROC Period 10–20, Strong 6–10. Many signals; require level + confirmation.
15m–1H (intraday): ROC Period 14–34, Strong 4–7. Sweet spot.
2H–4H (swing): ROC Period 20–50, Strong 3–6. Cleaner legs, fewer flips.
1D+ (position): ROC Period 50–100, Strong 2–5. Use for backdrop; trigger on lower TF.
Settings that actually matter (and how to tune)
ROC Period (default 32): lookback for comparison.
Shorter = earlier signals, more noise.
Longer = steadier bias, slower turns.
Strong Momentum Threshold (default 5): where you say “this is real thrust.”
Pick it by history: scroll back, mark thrusts that ran, and note their typical ROCI. Set the band slightly inside that value so you see the start of good moves.
Pattern cheatsheet
Impulse leg: ROCI above 0 making higher peaks → trend leg in progress.
Healthy pullback: ROCI dips toward 0 but doesn’t flip negative, then turns up → add/entry with trend.
Weak breakout / likely fail: Price pokes level but ROCI stays near 0 or rolls over quickly.
Divergence (lightweight): Price makes a higher high, ROCI peaks lower → momentum thinning; trail tight into HVNs.
Best combos (kept simple)
Volume Profile v3.2 [JopAlgo]: Use VAH/VAL/LVNs/POC for where. ROCI tells you if the break has juice.
Anchored VWAP [JopAlgo]: Reclaim/reject AVWAP with ROCI on the correct side of 0 for higher quality.
CVDv1 [JopAlgo]:
Yes: ROCI thrust + CVD Alignment OK + no Absorption → higher odds the move sticks.
No: ROCI thrust but Absorption red → don’t chase; wait for the fail/reclaim.
(Optional add: RVOL—high participation + strong ROCI is the A+ combo for breaks.)
Common mistakes this avoids
Buying a breakout while ROCI sits near 0 (no impulse).
Shorting a strong trend when ROCI is firmly > 0 (or > +5).
Treating every zero cross as a trade (it’s a heads-up, not an entry by itself).
Quick defaults to start
ROC Period: 32
Strong Threshold: 5
Process: Level → ROCI side/strength → (optionally) CVD quality → Execute with structure-based risk
Screenshots tip: show a level break where ROCI pushes through +5 and a pullback where ROCI turns up from ~0.
