01Definition
0.5 is a midpoint retracement reference. 0.618 is a Fibonacci reference. Neither predicts a reversal.
02Why it matters
A reference area can organize research without confirming a trade.
03What to check
- Explicit start and end of the measured move
- Selling, absorption, and renewed buyers near the area
- Current thesis, hygiene, and fresh-risk limits
04Healthy / Dangerous
Healthy
The area has independent demand evidence and defined invalidation.
Dangerous
A ratio substitutes for observed supply and demand.
05Beginner mistake
Calling a 0.618 touch a guaranteed bounce.
06Takeaway
Fib gives the area; behavior decides the case.
See the idea
- 01
A move from $1 to $2 has a midpoint at $1.50.
- 02
A 61.8% retracement from the high is about $1.382.
- 03
A touch of either level still needs demand evidence.
Trace it externally
Use an external chart with a clear measurement anchor, then Inspect for sampled flow. Meme Fast does not calculate or validate Fibonacci levels.
Go deeper
For an upward move, reference price = high − retracement fraction × (high − low). The 50% midpoint is commonly included in retracement tools but is not a Fibonacci ratio. Changing endpoints or timeframe changes the reference. Seller exhaustion, absorption, returning buyers, and a surviving thesis are evidence questions, not guarantees.
