GBPCAD - The Alert was the Abnormal SI and the entry was confirmed by Plutus, 90 pips.

...and the tip was given by me to my VIP members.

Abnormal SI of 96.6, nothing like that on the entire chart.

What does it mean?

Simple, that was a change in behavior which meant that price had a very hard time to move up. Market makers were absorbing you buy orders with sell orders and Plutus confirmed with break of Support with a PRS entry signal.
