the doted lines are trades which originate at one spot and terminate at the take profit point, blue for long red for short I think. the sharper the slope the more profit that was taken.
so in post 60, I am showing you in the middle, sell limit orders pending INSIDE the spread, I typically place orders inside the spread to take advantge of ignoraNT traders of any and all types.
I dont place stop loss orders to realize a loss, I place stop loss orders to lock in profits, so if I am up 10 pips I may set a stop loss order for 5 pips, so the minimum profit will be 5 pips. pending orders bigger than 5 lots are not really highlighted bu it is a graphical represenation with a line graph as to a visual of the volumne (total orders in lots) the more lots the further the "highlighting will continmue to the left. hope this helps!
