hi
the trailing stop loss tries to lock in some profit or make the loss minimum by taking the best profit price and then calculating the 50% loss from that price.
so if you bet at say back bet at 4 and the price dropped to 3 the trigger would take the 50% from the 3 price instead of the 4, so a loss of 50% from 3 is less than from 4, meaning the bet will be placed sooner.
some times it will lock in a profit, so it is good to tick trailing stop loss.
green up = green up when the price is correct
attempt to green up = a bet is placed at the green up price and wait for it to be matched
