hi
to check for the back/lay amount of money available, you use back/lay amount for the best price and back/lay amount2 for the next best price.
so, and trigger expression back_amount is greater than 100, the trigger will only place a bet if there is more than 100€ available at your set odds.
be carefull if you use amount2 as the traders use this to push the price in there direction,then cancel the bet quickly
