i assume that means that the rule will NOT fire if the selection has 2 unmatched or 1 unmatched bet, waiting to be matched.
if if has 3 unmatched bets (waiting to be matched) the rule will fire, if it as 4 unmatched bets (waiting to be matched) it will fire, 54 unmatched (waiting to be matched) it will fire and so on.
what does a condition of less than 1 unmatched bet (waiting to be matched) mean?
does it mean zero unmatched bets waiting to be matched?
could someone clarify for me please, i seem to have confused myself

thanks in advance
