I got a nice way to win very frequently

but i am unable to write a good script for it

the key is

play at 6 or 8 or 10
play for double at a time for loose so loose 12 in a row by playing for 6
the double the start from 1 to 2
and bet half of the time 
then double again from 2 to 4 and play 3 again
again from 4  8
by a win start over again

with a max of 1024
 
most of the time it will win, and otherwise lose less

is someone can write a script with this settings for 6 or 8 time
