Resistance Retests: Check Whether Support HoldsBitcoin / U.S. dollarBITSTAMP:BTCUSDTrade_Logic_AIA retest checks whether a broken level can take on a new role. When price breaks above resistance, a later pullback may find support in the same area. The break creates the possibility; the response during the pullback provides evidence of whether that role change is holding. First, identify the level before judging the retest. Look for an area where earlier advances repeatedly stalled, then look for a completed candle closing above it. A wick through resistance alone gives weaker evidence because price may finish the candle back inside its previous range. For this weekend review, the BTCUSD four-hour chart illustrates the importance of context: it shows a sharp decline followed by a modest rebound. The supplied zone at 80251-81156 is an area to study, supported by the largest shelf in the supplied volume profile and prior chart extremes. That context does not establish a successful resistance-to-support change. To illustrate that change, price would first need to reclaim the zone with a completed close above its upper boundary, then return to test it from above. Next, observe how the pullback behaves. A healthy retest often shows less forceful downward candles, overlapping price action near the former resistance, and closes that hold above or recover the area. A brief wick into the zone can be compatible with support holding. Repeated closes below it, followed by difficulty recovering it, weaken that interpretation. Check the sequence using completed four-hour candles through the last finished bar: resistance, a close above it, a return from above, and a subsequent response away from the area. Keep any unfinished candle out of the assessment. A touch alone does not confirm support, and even a convincing response can later fail. A common mistake is assuming every broken level must be retested. Price can continue without returning, or return and break straight through. Neither the revisit nor a successful hold is guaranteed. For practice, replay historical examples and record the evidence available at each completed candle. Before revealing what follows, define what would invalidate the proposed role change and set a hypothetical loss limit. Include failed retests and breaks with no return so the exercise does not become a collection of successful examples.
