After generating patterns by function:

if(adviseLong(PATTERN+FAST+2,0,
priceHigh(2),priceLow(2),priceClose(2),
priceHigh(1),priceLow(1),priceClose(1),
priceHigh(1),priceLow(1),priceClose(1),
priceHigh(0),priceLow(0),priceClose(0)) > 0)

I found some pattern information ratio way beyond usual 0-150 range:
EBCAfDHKIGlJ 750000

Is it ok, or I should delete these few rules manually?

This is ok. The information ratio is a ratio, meaning it can go up to infinity when the denominator goes down to zero. This can happen when there are patterns with similar returns.
