Support and resistance are price levels where the market has reacted before and is likely to react again: support is a level that has tended to halt declines, resistance a level that has tended to cap advances. They mark where buyers and sellers previously committed in size, so price has a memory there.
Target audience: Beginners who want to identify the horizontal levels that matter and understand why price reacts to them.

Levels turn an open chart into a map of where decisions get made. Most setups, entries, and stops are placed relative to a level, because that is where supply and demand are concentrated and where reactions cluster. Knowing the nearby levels tells you whether price has room to run or is about to hit a wall, and it tells you where a move becomes cheap to risk against. A trader without levels is navigating without landmarks.
A level matters because participants remember it. When price reverses sharply from a price, orders, stops, and emotions cluster there. The next time price returns, traders who missed the first move look to act, those who were trapped look to exit at breakeven, and fresh participants lean on the obvious line. That concentration of intent is what produces the reaction. Levels are not magic; they are crowds repeating behavior at prices that were significant the last time.
The best levels come from clear, decisive reactions: a sharp rejection, a strong launch, or a price that has been tested several times. Mark the level at the body cluster or the obvious turning point, not at every minor touch. Fewer, higher-quality levels beat a chart covered in lines. A level confirmed by multiple reactions over time, and visible on a higher timeframe, carries more weight than one drawn from a single small wick.
Price rarely respects a level to the exact tick. Treat each level as a zone a few ticks wide, because liquidity sits around a price, not on a single point. This matters for execution: placing a stop exactly at the line invites a noise-driven shakeout, while understanding the zone lets you give the level the small room it needs. The reaction is what confirms the level, so wait for evidence of a response rather than assuming the precise number will hold.
The most useful behavior of a level is the flip. When price breaks decisively through resistance, that old ceiling often becomes a floor: former resistance turns into support. The reverse is true for broken support becoming resistance. The logic is the crowd again: buyers who broke through defend their level on the pullback, and trapped sellers cover there. A retest of a flipped level, holding in its new role, is one of the cleaner entries technical analysis offers.
A level never trades in isolation; it trades inside a trend. Support in a strong uptrend is far more likely to hold than support in a downtrend, where each level tends to give way. Read the structure first, then use levels to time entries in its direction. The highest-quality setups stack the two: a with-trend pullback into a level that also marks the trend's last protected swing, so structure and level point the same way.
A market is rejected twice from 50, confirming it as resistance. On the third approach it breaks and closes above, then pulls back. The 50 level that twice capped price now acts as support: price holds 50 on the retest and continues higher. A trader who marked 50 from the first two rejections had the exact level to watch, entering long on the retest with a stop just below 50, where the role reversal would have failed.
A trader marks support and places a stop one tick below the exact line. Price dips a few ticks through the level on a wick, stops them out, then reverses hard in their original direction. The level held as a zone; the stop was placed as if it were a precise point. Treating the level as a small band and allowing for the wick would have kept the trader in the move the level actually delivered.
