how to store the last opened trade size in a variable ?

[bacharchoura1]

good day
kindly tell me how to save the LAST OPENED "buy" trade size in a variable and how to store the LAST OPENED "sell" trade size in a different variable so that i can use these 2 variables to determine the size of the next buy or sell position...
thank you
