False information.
First of all, 2 std is top 97.6% and 3 std is stop 99.7% since "top" means cumulative.

Second, it is wrong to say that current price is 3 std "departure" from the mean... since bollinger band simply calculates new mean after every price change, thus it always measures 2 std away from the mean.

Since the price is crashing without making a spike back up, the std deviation is getting smaller, meaning the volatility is decreasing, thus, the bollinger band would simply constrict and indicate decreasing volatility in price. Contrary to your statement, Bollinger band does not predict that the price will spike up but only a small spike, if there will be any.

I suggest you re-touch up on your statistics and stop spreading false information.
