How to draw support and resistance with explicit rules

Step 1: choose one timeframe and enough history

For a reproducible example, select 120 closed candles on one fixed timeframe. This lookback is a study parameter, not a proven minimum. Keep the price axis, session and adjustment settings recorded. A higher or lower timeframe can be reviewed separately, with its own levels.

• Swing review: start with daily candles, then refine on four-hour.
• Day-trading review: start with hourly, then refine on 15-minute.
• Keep the price axis and timeframe label visible in screenshots.

Step 2: mark repeated reactions

One custom rule identifies a pivot high only when its high exceeds the highs of two closed bars on each side; reverse the comparison for a pivot low. It is known two bars after the pivot, not on the pivot bar itself. Define how far apart repeated reactions must be before calling them separate tests; several neighboring candles need not be independent evidence.

Step 3: draw a zone instead of an exact line

For an illustrative fixed-width zone, center it on the confirmed pivot and set total width to 0.5 times the 14-period ATR measured at confirmation. Thus a pivot at 100 and ATR of 4 produces a band from 99 to 101. Freeze that width for later evaluation; recomputing it after the outcome changes the rule. These parameters are examples, not optimized settings.

• Support sits below current price and contains prior buying reactions.
• Resistance sits above current price and contains prior selling reactions.
• Old resistance can become support after a close above and a successful retest.
• Old support can become resistance after a close below and a failed recovery.

Step 4: define failure before planning a trade

Write a failure rule before the next move. For example, record a break when a closed candle finishes outside the band, then separately record whether a later retest closes on the other side. State the maximum retest window and timeframe. A lower-timeframe touch is not the same event as the original timeframe closing outside the zone.

Common drawing mistakes

Retain the original chart and zone coordinates. Do not move a boundary to fit the later outcome. If the display becomes crowded, use a fixed selection rule such as the nearest zone above and below current price, and keep the omitted zones in the study record.
