Support & Resistance
The levels where decisions happen.
If candlesticks are the market's handwriting, support and resistance are the lines on the page. A candle pattern in the middle of nowhere is trivia; the same pattern at a level the market has defended twice is a trade idea. This module is about finding those places honestly, without decorating the chart into fiction.
Zones, not lines
Support is an area where falling price has repeatedly found buyers; resistance is where rising price has repeatedly found sellers. Area is the operative word. The market is an auction of millions of participants, and their orders cluster in a band, not at a single tick. Draw levels as zones a little taller than you'd like, and you'll stop being shaken out by wicks that pierced a line by a few cents and reversed exactly as the level predicted.
The four honest sources of levels
Prior highs and lows. The most recent meaningful swing points, plus the big obvious ones (yesterday's high, last month's low, the all-time high). These are the levels everyone sees, which is precisely their power.
Trendlines and channels. A line connecting two or more rising lows (or falling highs) turns support into something diagonal: a trend. Two touches draw a line; the third touch makes it interesting. A parallel line over the highs makes a channel. Honesty rule: a trendline you had to bend, or that ignores half its wicks, is an opinion in costume.
Moving averages. The widely watched averages, the 20, the 50, the 200, act as moving zones because so many participants anchor decisions to them (Module 5 covers the mechanics). In a trend, pullbacks to a rising average are among the most-watched reunions in trading.
Round numbers. $100 on a stock, $50,000 on Bitcoin. Human brains anchor to round figures, so orders pile there. It's not mystical; it's psychology with a limit order.
The flip: yesterday's floor, tomorrow's ceiling
The single most useful behavior levels exhibit: broken support tends to act as resistance when revisited, and broken resistance tends to act as support. The mechanism is trapped participants. Whoever bought at the old support is now underwater; when price climbs back to their entry, relief-selling appears exactly there. The retest of a broken level is one of the most studied moments in technical trading, and the candle patterns from Module 2 are how you read who's winning it.
Where the ebook goes deeper
Part IV of The Complete Trader turns levels into a complete method: how to mark a chart in five minutes without decorating it, which levels justify a trade, and worked examples where level, candle, and position size line up into one sized decision.
Questions, answered straight
How many touches make a level valid?+
Two touches suggest a level; three make it credible. But freshness matters as much as count: a level tested five times this month tells you more than one from three years ago. Draw fewer, more obvious levels, and let the untouched chart breathe.
Why does support and resistance work at all?+
Two honest reasons: memory and self-fulfillment. Traders remember where they bought, sold, or regretted not acting, so orders cluster at those prices. And because thousands of participants draw the same obvious levels, their collective orders make the level real. It works until everyone leaning on it is forced out, which is what a breakout is.
Do support and resistance levels expire?+
They fade rather than expire. Each successful test spends some of the orders resting there; a level defended four times has fewer defenders left for the fifth. Old untested levels weaken as the participants who created them move on. Treat levels as evidence with a shelf life, not laws.
