I have tried time and time again to create my own LUA:

chance  = 70.21 -- I think that's 1.41 ?
basebet = .000001
bethigh = true

After 1 loss -- increase by 150%
After 1 win -- Decrease by 50%

After 3 wins in a row -- reset to basebet
After 2 losses in a row -- Switch Under/Over
After 3 wins in a Row -- Switch Under/Over

I don't know how to code the rest.
