0.08 @ 1.2660 If you calculate the difference between 1.2660 and 1.2578 you get 82 pips
30 divided by 82 gives 2 , so you go 2 steps down for lot size of this trade which is 0.08

0.16 @ 1.2715 if you calculate the difference between 1.2715 and 1.2660 you get 38 , 30 divided by 38 is 1 so the lotsize for this trade is 0.16


it is this particular trade that closes all the other trades

thanks , your question will really shed more light on lot size calculation

Also i noticed you are not using eurgbp or eurchf ( am focusing on those 2 for now)
