After many losses in a row, is a winning trade more likely?

Not if trades are independent: the probability of the next outcome is the same as before the streak. If trades are correlated, a streak of losses more often signals conditions that keep producing losses, which argues for caution rather than for a larger position.

Is the gambler's fallacy the same as the hot-hand fallacy?

They are opposite beliefs built on the same error. The gambler's fallacy expects a reversal after a streak; the hot-hand belief expects continuation. Both assume that past independent outcomes change the next probability.

Gambler's fallacy in trading

The gambler's fallacy is the belief that after a run of one outcome the opposite outcome becomes more likely, so that a win is 'due' after several losses. For independent trades the probability of the next result does not depend on the streak that preceded it.

The mistake in one calculation

With a 50% win rate and independent trades, the chance that six trades in a row all lose is 0.5⁶ = 1 in 64. That number is often quoted to argue that after five losses the sixth trade is very likely to win. It is not: once five losses have happened, the only uncertain event is the sixth trade, and its probability of losing is still 0.5. The 1-in-64 figure described the whole sequence before it started, not the last trade after the first five are known.

The mirror image, the hot-hand belief, holds that a winner is more likely after several winners. Both treat a sequence of independent events as if it had memory.

Where it shows up in trading behavior

Raising size after a string of losses because the next trade 'has to' work, which is the logic of a martingale.
Skipping a valid signal after several winners because a loss feels overdue.
Abandoning a stop-and-reverse rule halfway through a streak, which changes the strategy that was tested.
Reading a long streak as proof that the market is 'rigged' rather than as a normal event for the measured win rate.

When a streak does carry information

Trades are not coin tosses. Consecutive trades in one session share a regime, so outcomes can be correlated. When that is the case, a streak may say something about the current market, for instance that a mean-reversion rule is trading into a trend, but it then argues for continuation of the bad conditions, not for a reversal of luck. The honest test is empirical: compare the win rate after a loss with the win rate after a win on a large sample. If the two are similar, the trades behave as independent and the streak predicts nothing.

That comparison needs a trade list with times and results. In Senzoukria the journal's CSV export contains the entry time, side, prices, quantity and P&L of each row, and the journal dashboard's Streak card shows the current and extreme runs as descriptions, not as predictions.

Practical safeguards

Fix size by a rule decided before the session, never by the length of the current streak.
Know the streak your win rate makes likely; the longer ones stop being surprising once the numbers are known.
Separate the question 'is this a normal streak' from 'has the market changed', and answer the second one with data other than the streak itself.
