cracked it i think

chance  = 49.95
bethigh = true
target  = 1
basebet = balance/10000
nextbet = basebet
more    = balance
read    = balance
los     = 0
won     = 0
function dobet()
if (win) then
    won+=1
else
    los+=1
end
 if (won == 1) then
     nextbet = previousbet*1.2
    won     = 0
end
 if (los == 1) then
     nextbet = previousbet*1.2
     los     = 0
end
  if balance > more and win then
      nextbet = balance/10000
     more    = balance
 end
 if balance > target then
    stop()
end
end
