Day 31: Support & Resistance — The Price Walls
Where prices bounce, and where they stall — the floor and ceiling of every trade

📖 The Bouncy Ball and the Ceiling
Drop a rubber ball. It bounces off the floor. Throw it up. It hits the ceiling and falls back. The floor is "support" — the price level where buyers consistently step in. The ceiling is "resistance" — where sellers consistently step out.
Now imagine the ball breaks through the ceiling. That old ceiling becomes the new floor. This is the most important concept in all of technical analysis — called Role Reversal.
Master this and you've mastered the foundation of chart trading. 🎾

Support Level
A price level where buyers consistently outnumber sellers — price tends to "bounce" upward.
Example: NIFTY has bounced from the 21,500 level four times in the past year. 21,500 = support!
Why? At that price, many buyers are sitting with limit orders: "I'll buy NIFTY if it comes to 21,500." Their collective buying creates a floor.
Trading strategy: Buy near support with stop loss just below it. Risk is defined and small.

Trading strategy: Buy near support with stop loss just below it. Risk is defined and small.
Resistance Level
A price level where sellers consistently outnumber buyers — price tends to "fall back" downward.
Example: Infosys has failed to break above ₹1,800 three times. ₹1,800 = resistance!
Why? Many sellers have limit sell orders at ₹1,800: "If Infosys reaches ₹1,800, I'll take profits." Their selling creates a ceiling.
Trading strategy: Consider taking profits near resistance. Or wait for a confirmed breakout above it.

Role Reversal — The Magic Principle
🔄 Old Resistance Becomes New Support
⬆️ Price breaks above ₹500 resistance — closes at ₹520
🔄 ₹500 is now SUPPORT — old sellers become buyers!
⬇️ Price pulls back to ₹500 — buyers step in, price bounces!
💡 This is role reversal. One of the most reliable patterns in markets.
Trendlines — Dynamic Support/Resistance
In an uptrend: Connect the higher lows → Rising support trendline!
In a downtrend: Connect the lower highs → Falling resistance trendline!
Price touches the trendline + bullish candlestick pattern = strong buy signal
Price breaks below the trendline on high volume = trend possibly ending — review position
In a downtrend: Connect the lower highs → Falling resistance trendline!
Price touches the trendline + bullish candlestick pattern = strong buy signal
Price breaks below the trendline on high volume = trend possibly ending — review position
🎯 Today's Takeaway:
Support = floor (price bounces up). Resistance = ceiling (price bounces down). Role reversal = old resistance → new support after breakout. This is endlessly useful in actual trading. Tomorrow: Moving Averages — the indicators that never lie about the trend!
