Support, Resistance, and Volume

Price doesn't move in a straight line. It travels between floors and ceilings. Support is the floor, the price level where buyers keep stepping in to stop the fall. Resistance is the ceiling, where sellers keep showing up to cap the rise. These levels are where the real action happens, where trades begin and end, because they're the prices the whole market remembers and reacts to.

A few truths that make levels useful. First, a level is a zone, not a hairline. Don't obsess over a level at exactly $100.00, think of it as the $99.50 to $100.50 area. Second, the more times price has reacted at a level, the stronger it is. Third, and this is the one beginners miss: when a resistance ceiling finally breaks, it often flips and becomes support on the way back down. Old ceilings become new floors. That role reversal is one of the most reliable things in all of charting.

Then there's volume, your fuel gauge. Volume is how many shares actually traded during a candle, shown as the bars at the bottom. It tells you whether a move means anything. A breakout through resistance on heavy volume is conviction, real buyers piling in, and it tends to hold. The same breakout on weak volume is a whisper, and whispers are often traps that snap right back. Big move plus big volume equals real. Big move plus weak volume equals be careful.
