CIDE DICTIONARY

martingale, n. [F. martingale; cf. It. martingala a sort of hose, martingale, Sp. martingala a greave, cuish, martingale, Sp. almártaga a kind of bridle.].

•  A strap fastened to a horse's girth, passing between his fore legs, and fastened to the bit, or now more commonly ending in two rings, through which the reins pass. It is intended to hold down the head of the horse, and prevent him from rearing.  [1913 Webster]
•  A lower stay of rope or chain for the jib boom or flying jib boom, fastened to, or reeved through, the dolphin striker. Also, the dolphin striker itself.  [1913 Webster]
•  The act of doubling, at each stake, that which has been lost on the preceding stake; also, the sum so risked; -- metaphorically derived from the bifurcation of the martingale of a harness. Called also Martingale strategy. Such a betting strategy does not change the overall likelihood of winning, but in a short run it increases the probability of winning a small sum, balancing it against an increased probability of losing a large sum.  Thackeray.  [1913 Webster]
