Fibonacci Trading

Fibonacci levels identify high-probability zones where price tends to react — for entries on pullbacks and targets on extensions.

Prerequisites

No dependencies required. Just provide a swing high and swing low price — Claude calculates all Fib levels instantly. Enhanced with Groww MCP (auto-identifies swings from candles) or yfinance.

Data Needed

1. Swing high and swing low: From fetch_historical_candle_data or user-provided prices
2. Current price: get_quotes_and_depth from Groww, or user-provided
3. For precise calculation, you can compute in Python:

   diff = swing_high - swing_low
   levels = {
       "23.6%": swing_high - diff * 0.236,
       "38.2%": swing_high - diff * 0.382,
       "50.0%": swing_high - diff * 0.500,
       "61.8%": swing_high - diff * 0.618,
       "78.6%": swing_high - diff * 0.786,
   }
   

Retracement Levels (Entry Zones)

After a significant move up, price often pulls back to these levels before continuing:

Level	Character	Trading Implication
23.6%	Shallow pullback	Strong trend — buyers eager, enter aggressively
38.2%	Normal pullback	Healthy trend — standard entry zone
50.0%	Deep pullback	Trend weakening but viable — enter with caution
61.8%	Golden ratio	Last stand for the trend — high reward if it holds
78.6%	Very deep	Trend likely failed — avoid or use tight stop

For downtrend retracements (price bouncing up):

Same levels but inverted — measure from swing high down to swing low.

Extension Levels (Profit Targets)

After a retracement completes and price resumes the trend:

Level	Use
100%	Measured move — equal to the prior swing
127.2%	Conservative target — good for partial profit
161.8%	Standard target — most common for swing trades
200.0%	Extended target — for strong trends
261.8%	Full extension — rare, only in powerful moves

Calculating Extensions

# For uptrend: price resumed from point C (retracement low)
ext_127 = C + (swing_high - swing_low) * 1.272
ext_161 = C + (swing_high - swing_low) * 1.618
ext_200 = C + (swing_high - swing_low) * 2.000

How to Draw Fibs

1. Identify the swing: Find the most recent significant high and low (at least 5% move)
2. Direction matters:
   • Uptrend retracement: Anchor at swing low, drag to swing high
   • Downtrend retracement: Anchor at swing high, drag to swing low
3. Use the right swing: The most recent completed swing, not one still in progress
4. Multiple swings: You can draw Fibs from different timeframes. When levels from different swings overlap, that's a confluence zone (very strong).

Confluence Zones

The most powerful Fibonacci levels are where they align with other technical factors. These zones have the highest probability of price reaction.

Confluence Combination	Strength
Fib level alone	Moderate
Fib + horizontal S/R	Strong
Fib + moving average (SMA50/200)	Strong
Fib + trendline	Strong
Fib + S/R + MA	Very strong
Fib from multiple timeframes overlapping	Very strong

Practical Examples

• Fib 38.2% from daily swing aligns with SMA50 → strong buy zone
• Fib 61.8% from weekly swing aligns with horizontal support from 3 months ago → high-probability entry
• Fib extension 161.8% aligns with a round number (Rs.2,000) → likely profit target

Fibonacci Trading Rules

1. Don't use Fibs in isolation — they work best as confirmation alongside S/R, volume, and indicators
2. Zone, not line — treat each level as a zone (±1-2%), not a precise price
3. Wait for reaction — don't blindly buy at a Fib level. Wait for a reversal candle (hammer, engulfing, etc.)
4. Strongest entries: Fib 38.2% to 61.8% zone in a healthy trend with volume confirmation
5. If 78.6% breaks: The trend is likely over — exit or reverse
