A walkthrough of this example
This is narration of the published facts on this page. It does not add new numbers, and it is not a signal.
-
Step 1
What the chart is showing
On Bitcoin daily, a prior high around 22 May 2025 later comes back into the picture after a July close through that area. In August, price trades back toward that old high and holds above it on the closes in this window. That’s a common “old resistance tried as support” picture — a description of these bars, not a rule with an edge.
-
Step 2
How to read it as a student
Ask: did the break close through the prior high, and did the later test stay on this side of it? The published facts mark the May high, the 10 July close, and the early-August retest lows. Walk those three dates on the chart before you invent a story around them.
-
Step 3
What to keep honest
This is an educational example from public Kraken daily bars, not a trade I took and not a signal. A hold in this window does not mean the same shape will hold next time. Fills, fees and slippage are not known from these closes.
