CRR Bill Williams

These are SMMA based on the average price (high+low/2):
Jaw – Blue
Slow line, the base of the trend.
Teeth – Red
Medium speed.
Lips – Green/Lime
The fast one, the one that touches the price first.
Trend reading with the Alligator:
🟢 Uptrend (trendUpAlligator):
Lips (green) > Teeth (red) > Jaw (blue)
The alligator is awake and eating UP.
🔴 Downtrend (trendDownAlligator):
Lips (green) < Teeth (red) < Jaw (blue)
The alligator is eating DOWN.
⚪ Range / sleeping market (trendNeutral):
The lines cross, get tangled, without a clear order → better NOT to trade aggressively there.
In the HUD it shows it as:
UPTREND (green)
DOWNTREND (red)
RANGE (gray)
2️⃣ Fractals (▲ and ▼ arrows)
Fractal High (▲ green): possible local top (resistance).
Fractal Low (▼ red): possible local bottom (support).
They serve as:
Points where the price can break through to continue.
Areas where you can place stop losses or breakouts.
3️⃣ AO and AC (trend strength)
AO (Awesome Oscillator): difference of moving averages (5 and 34 of the average price).
AO > 0 → bullish pressure.
AO < 0 → bearish pressure.
AC (Accelerator): AO – average of AO.
AC > 0 → acceleration in favor of the movement.
AC < 0 → the movement slows down or goes against the trend.
In the HUD you see:
AO > 0 | AC > 0 → good tailwind.
AO < 0 | AC < 0 → strong headwind. 4️⃣ Bill Williams MFI (GREEN, FADE, FAKE, SQUAT)
This MFI is based on the candle range/volume and then compares it to the previous candle:
GREEN (Lime) → mfiUp + volUp
Price and volume rise together → real, strong momentum.
FADE (Gray) → mfiDown + volDown
Everything is dying down, price and volume fall → exhaustion.
FAKE (Orange) → mfiUp + volDown
Price rises but volume falls → deceptive movement.
SQUAT (Fuchsia) → mfiDown + volUp
Strong fight between buyers and sellers → explosive zone.
The color you see in the "MFI" HUD is:
Green → healthy momentum
Gray → fading out
Orange → deception
Fuchsia → strong fight, a big move may be coming
5️⃣ Candle Colors (barcolor)
Your script paints the candles like this:
💚 StrongBull (strong buying)
Bullish Alligator (Lips > Teeth > Jaw)
AO > 0
AC > 0
MFI = "GREEN"
→ Bright LIME candle:
👉 strong upward trend, ideal time to look for buying opportunities.
❤️ StrongBear (strong selling)
Bearish Alligator (Lips < Teeth < Jaw)
AO < 0
AC < 0
MFI = "GREEN"
→ Strong RED candle:
👉 strong downward trend, ideal for looking for selling opportunities.
🩵 Normal bullish trend:
Bullish Alligator but without all the strength conditions → TEAL (bluish-green) candle.
🟥 Normal bearish trend:
Bearish Alligator but without full strength → MAROON candle.
⚪ Sideways market:
Everything mixed → translucent GRAY candle (color.gray 60).
👉 Not the best time to enter aggressively. 6️⃣ BUY / SELL Signals (triangles)
✔️ BUY Condition (longSignalCond)
The code requires:
Bullish Alligator → Lips > Teeth > Jaw
AO > 0
AC > 0
MFI = GREEN or SQUAT
close > Lips (green lips) → the price is already above the fast moving average.
When fulfilled:
A green “BUY” triangle appears below the candle.
In the HUD:
Trend: BULLISH (green)
AO / AC: > 0
MFI: GREEN or SQUAT
BW Setup: “SIGNAL: BUY”
Context: “Buying Pressure”
👉 Idea for making money (buys):
Wait for the Alligator to be in a bullish order.
Check that the HUD says BULLISH and AO/AC > 0.
Check MFI: GREEN or SQUAT.
As soon as the BUY triangle appears and the candle is lime/teal, you can:
Enter a buy position.
Place the stop loss below the last fractal low (▼).
Close partially when:
MFI changes to FADE/FAKE or
The candles change to gray/maroon or
The Alligator becomes entangled (loses its order).
❌ SELL Condition (shortSignalCond)
The code requires:
Bearish Alligator → Lips < Teeth < Jaw
AO < 0
AC < 0
MFI = GREEN or SQUAT (strength but downwards)
close < Lips → price below the lips.
When fulfilled:
A red “SELL” triangle appears above the candle.
In the HUD:
Trend: BEARISH
AO / AC: < 0
MFI: GREEN / SQUAT
BW Setup: “SIGNAL: SELL”
Context: “Selling Pressure”
👉 Idea for making money (sells):
Wait for the Alligator to be in a bearish order.
HUD in BEARISH, AO/AC < 0.
MFI in GREEN or SQUAT.
When the SELL triangle appears with a red/maroon candle:
Enter a sell position. Stop above the last fractal high (▲).
Partial exit when:
MFI changes to FADE/FAKE,
The candles turn gray/teal,
Or the Alligator becomes tangled.
7️⃣ When NOT to trade
Avoid:
HUD → “RANGE”
Mostly gray candles.
AO and AC mixed (one >0 and the other <0).
MFI constantly in FAKE/FADE.
In these situations, the system tells you: slow or deceptive market → not suitable for serious trades.
8️⃣ Ultra-short summary (golden rule)
BUY:
Alligator ordered UP (green > red > blue).
AO > 0 and AC > 0.
MFI = GREEN or SQUAT.
Strong green candle (lime/teal) + BUY triangle.
Even better if it breaks a previous fractal low upwards.
SELL:
Alligator ordered DOWN (green < red < blue).
AO < 0 and AC < 0.
MFI = GREEN or SQUAT.
Red/maroon candle + SELL triangle.
Even better if it breaks a fractal high downwards.
Jaw – Blue
Slow line, the base of the trend.
Teeth – Red
Medium speed.
Lips – Green/Lime
