at 20k-29k lot size should be adjsuted to 0.2 and all trades closes at unrealised account profit of 8000 or unrealsed loss of 4000. at 30-39 k lots be 0.3 and all trades closes at unrelased profit of 12000 or unrelased loss of 6000 ...same logic as account balance grows

i currently have this EA which has a fixed lot size of 0.1 and can make multiple trades per each being 0.1 lots ... all trades are closed if the total unrealised profit is $4000 or unrealised loss is $2000

my problem now is i want to switch from fixed lot to auto lot such that if my balance is 10-19k we mainting the 0.1 lots and profit/loss hower at 20-29k i want all trades to close at 8000 unrealised profit or 4k loss and mainting continuing increasing both my lot sizes and unrealised loss/profit targets
