Support and resistance from swings, not round numbers alone

Round numbers are busy. That does not make every half-cent or ten-point print a level worth defending in your plan.

When we teach intraday technical analysis, we start from swing highs and lows that the market has already respected twice or more. A prior session’s rejected high, a lunchtime low that held for ninety minutes, a weekly open still in play — these earn ink. A clean 8,000 on an index might matter because it coincides with a swing, not merely because it is round.

Failed breaks deserve equal respect. Price that drives through a marked resistance and closes back below often leaves a pocket of trapped inventory. That pocket can become tomorrow’s magnet — or today’s short trigger if your plan allows fades. We do not prescribe the direction; we insist the level is real before the story begins.

Homework we give coaching clients: strip your chart to candles and volume only, remove horizontal lines you drew in a hurry, then re-mark a maximum of three levels for the next session. If you need seven lines to feel safe, the problem is usually size, not geometry.
