Martingle strategy in theory works if we have an unlimited deposit, and we can find a pair with ZERO SPREAD. To see why zero spread is important, let's assume the common amount of spread, 2 pips, for EUR/USD pair. Opening positions with base lot sizes: 1, 3, 6, 12, 24, ... will give you a loss even the fourth position reaches take profit! Here is the math behind it:

P(4) = (TP-SP)*(12+3)-(SL+SP)*(6+1)

if TP = 30, SL = 60 and SP=2, then

P(4) = (28)*(15)-(62)*(7) = -14 pips!

Therefore, even if your fourth position reaches the TP point, you loses the trade! This can be avoided by adjusting TP and SL points 2 pips everytime a new position opens, but it requires to tolerant to a divergence in TP/SL range that eventually kills your account.

One might argue that we can increase TP to cover losses from spread. Let's take a look at our example in a more general case where, according to Martingle strategy, SL = 2*TP,

P(4) = TP - 22*SP

This means that with SP=2 pips, we need to set a TP > 44 pips but if we go one more level to open fifth position, this TP would not be enough to cover the loss.
