That's not martingaling. What you did was scale in or pyramid in to an existing trade in the anticipation that your dip is a retracement rather than a reversal.Quote from jimmyjazz:
Are there any studies out there that look at "one time" double-down strategies, or other limited versions of Martingale? I have, on occasion, bought more of a stock I remained bullish on when it took an unexpected dip. It has usually worked out, but I am well aware that I might have just been lucky.
Martingaling is where you exit a trade because it is a loser but then you increase the size (typically double) of the next trade hoping to win back what you lost. The theory is that if you have a big enough trading account and no upper limit to how much size you are allowed to bet or trade, you'll eventually recoup all of your losses. In practice it usually ends in disaster if you do it enough times.
Scaling in or pyramiding in is a strategy technique. Martingaling is pure money management (and bad MM at that).
