I found this script on dicebot site, and I was wondering if there is any way to implement code that would set maximum chance to 98%. Problem is that after long streaks of red, script tries to increase chance above 98% and then ofc it stops betting.
Yes, of course. A simple check when the chance is being calculated will stop that... the question is, what do you want to happen when it gets to 98%? Just continually bet 98% or should it "reset"? 
This code will simply set the chance to 98 if it tries to increase it over 98%... so once it hits 98, it will stay at 98 until a win causes it to drop (assuming winpercent is always going to be < 1):
NOTE: I HAVE NOT TESTED THIS CODE! I make no guarantees it will work, use at your own risk
Code:
basebet = 0.00000001
chance = 80
maxchance = 98
losepercent = 1.03
winpercent = 0.99
lossbet = 2
winbet = 1.12
bethigh = false
nextbet = basebet
function dobet()
if profit > 0.0000000000001 then
print(profit)
resetstats()
nextbet = basebet
chance = 80
end
if win and profit < 0.000000000001 then
print("We Won")
print(profit)
chance = lastBet.chance * winpercent
if chance > maxchance then
chance = maxchance
end
nextbet = lastBet.amount * winbet
bethigh = false
end
if win == false and profit < 0.0000000001 then
print("We Lose")
print(profit)
chance = lastBet.chance * losepercent
if chance > maxchance then
chance = maxchance
end
nextbet = lastBet.amount * lossbet
bethigh = false
end
end

Thank you in advance.
You're welcome 
and is a little bit faster on the bets like 25% faster than previous version of the bot
