Martingale (betting system)
A continuous sequence of martingale bets can thus be partitioned into a sequence of independent rounds. As the single bets are independent from each other and from the gambler's expectations , the concept of winning "streaks" is merely an example of gambler's fallacy , and the anti-martingale strategy fails to make any money. Blackjack, however, is less advantageous than a coin flip. When people are asked to invent data representing coin tosses, they often do not add streaks of more than 5 because they believe that these streaks are very unlikely. The straight martingale is one of the riskiest betting systems any gambler could use. But see also dollar cost averaging.
Blackjack Betting Systems: The Martingale Progression
A martingale is any of a class of betting strategies that originated from and were popular in 18th century France. The simplest of these strategies was designed for a game in which the gambler wins the stake if a coin comes up heads and loses it if the coin comes up tails.
The strategy had the gambler double the bet after every loss, so that the first win would recover all previous losses plus win a profit equal to the original stake. Since a gambler with infinite wealth will, almost surely , eventually flip heads, the martingale betting strategy was seen as a sure thing by those who advocated it.
None of the gamblers possessed infinite wealth, and the exponential growth of the bets would eventually bankrupt "unlucky" gamblers who chose to use the martingale. The gambler usually wins a small net reward, thus appearing to have a sound strategy. However, the gambler's expected value does indeed remain zero or less than zero because the small probability that the gambler will suffer a catastrophic loss exactly balances with the expected gain.
In a casino, the expected value is negative , due to the house's edge. The likelihood of catastrophic loss may not even be very small. The bet size rises exponentially. This, combined with the fact that strings of consecutive losses actually occur more often than common intuition suggests, can bankrupt a gambler quickly.

You note there were a few wins interspersed with the mostly losses, but you had to have had 12 more max bet losses than wins perhaps 18 losses and 6 wins? You must realize that you were required to start placing max bets after only 7 consecutive losses. If you count your double loss on your split pair as two hands, you actually began your unfortunate series of losses by losing 10 hands in a row.
How unusual is this? If I were flipping a coin, with heads being a win, and tails a loss, the odds against me coming up tails 10 times in a row would be about to Blackjack, however, is less advantageous than a coin flip.
