Fast answer
Bollinger Bands alerts need volatility context and proof.
Before using a Bollinger Bands crypto signal, check the band length, deviation setting, source chart, time frame, asset trend, squeeze or breakout rule, stop plan, target logic, update trail, and final status. A band touch by itself is not a complete trade call.
If the provider only posts a chart with price outside a band, treat it as a chart observation until the signal includes risk and follow-up records.
Band checks
What to inspect in a Bollinger Bands signal.
Settings
Record the moving-average length, deviation setting, source price, chart time frame, and whether the provider changed settings after the alert.
Trend state
Band touches can continue during strong trends, so the signal needs trend context instead of a simple overbought or oversold label.
Squeeze logic
If the call cites a squeeze, check the breakout trigger, fakeout rule, volume context, invalidation, and missed-entry label.
Final record
The alert should connect the band event to updates, stopped trades, partial exits, and final close status.
Source context
Bollinger Bands describe volatility, not certain direction.
TradingView's Bollinger Bands help page describes the tool as three bands around price, usually using a middle moving average and bands set by standard deviation. It also warns that price can keep walking along a band in strong trends. That is exactly why a signal record needs confirmation and a close note.
Review standard
Bollinger Bands calls should show the full path.
A reviewable Bollinger Bands record includes source chart, settings, time frame, alert timestamp, setup logic, entry rule, invalidation, stop, target, update trail, and final status. Missing settings, cropped screenshots, or deleted failed squeezes should lower confidence.
