If function question

[natebyerly32]

I'm trying to create a formula that replicates winning based on the martingale style of gambling for roulette. Odds would be 18/38 that you win each hand. You would begin with a 5 dollar bet, if you lost your next bet would be for 10 dollars, if you lost that bet your next bet would be 20 dollars. Every time you win you pocket the 5 dollars in profit and would then bet a new 5 dollars, everytime you lose you would double your bet. I was looking for some help with possibly using an if function in order to create a scenario of 1000's of games played in excel. Thanks

in bet c3
C3 = =IF(AND(B3="lose",B2="lose"), C2*2,5)
in result D3
=IF(B3="win",MAX($D$2:D2)+5,0)
