How the Mechanism Operates
Support and resistance are not exact magical lines; they are psychological zones where institutional order flow clusters.
When price bounces from ₹1,000 multiple times, buyers who missed out regret not buying, while short sellers regret not covering. When price returns to ₹1,000, both groups inject fresh buy orders, reinforcing the support zone.
However, each test of support absorbs resting buy liquidity. Contrary to retail belief, a 4th or 5th re-test of support indicates impending breakdown rather than strength. When support breaks, trapped buyers panic-sell, and new breakout short sellers enter, flipping the broken level into a formidable overhead resistance ceiling.
Flawless Polarity Flip on Blue Chip IT Stock
TCS consolidated below a major multi-month resistance ceiling at ₹3,900 for 14 weeks.
On high volume, TCS broke out above ₹3,900, reaching ₹4,020, followed by a low-volume 4-day pullback to ₹3,905.
The previous resistance acted as rock-solid new support, launching a second rally leg to ₹4,250 (+8.8%).
★ Entering on the re-test of a broken polarity level offers superior Risk-to-Reward compared to chasing the initial breakout candle.

Common Pitfalls & Remedies
Why it happens: Subjective trendlines lead to confirmation bias and low-probability trades.
Remedy: Focus primarily on clear horizontal structural swing highs/lows and high-volume nodes.
Frequently Asked Questions
Why does broken resistance turn into support?
Traders who shorted at resistance want to exit at breakeven when price pulls back to it, while breakout buyers who missed the initial move add fresh positions, creating a wall of buy demand.
