Fast answer
Fibonacci signals are only as clear as their anchor points.
Before using a Fibonacci crypto signal, check the high and low points used to draw the levels, chart time frame, whether the chart is linear or log scale, entry trigger, invalidation, stop plan, target logic, update trail, and final status.
If the provider does not show the swing points used to draw the retracement, the level is not reviewable.
Fib checks
What to inspect in a Fibonacci signal.
Swing anchors
Record the exact high and low points used to draw the retracement and whether they were changed after price moved.
Level meaning
Check whether the provider treats the level as support, resistance, entry, target, or invalidation.
Chart scale
For highly volatile crypto charts, note whether the provider uses linear or log scale and whether alerts match that view.
Confirmation
A level should be paired with a trigger, risk boundary, update rule, and final close record.
Source context
Fibonacci retracement levels are drawn from two extremes.
TradingView's Fibonacci retracement help page explains that the tool connects two extreme points and divides the distance into horizontal levels. It also notes log-scale considerations for highly volatile assets such as crypto. That makes anchor transparency essential.
Review standard
Fibonacci calls should preserve the original chart.
A reviewable Fibonacci record includes original chart, anchor points, time frame, scale, alert timestamp, level meaning, confirmation rule, invalidation, stop, target, update trail, and final status. Redrawn levels after the move should be labeled clearly.
