Before optimizing a strategy, define what would make you reject it.
A high profit factor is not enough if the result depends on one month, one symbol, one spread assumption, or a handful of trades. I prefer to write the failure conditions first: maximum tolerable drawdown, minimum trade count, cost sensitivity, parameter stability, and acceptable degradation out of sample.
This changes optimization from “find the best settings” into “search for configurations that survive reasonable stress.”
What is the first condition that makes you reject a backtest?

QuantMatrix Candle Patterns: How to Read Candlestick Signals Correctly
18 agosto 2026, 19:24
Candlestick patterns are among the most widely used tools in price action analysis. Patterns such as Hammer, Engulfing, Morning Star and Shooting Star are easy to recognize in theory, but manual identification can become subjective when dozens or hundreds of candles must be analyzed...

QM Candle Timing Meter es un indicador gratuito para MetaTrader 5 diseñado para responder a una pregunta sencilla: ¿Cuánto me he retrasado en la vela actual? Una señal de trading puede seguir siendo técnicamente válida, aunque el momento de la entrada ya haya cambiado significativamente. Por ejemplo, entrar durante los primeros minutos de una vela H1 es muy diferente a entrar cuando ya ha transcurrido el 90 % de esa vela. QM Candle Timing Meter mide continuamente la posición temporal de la vela

A valid signal does not always mean a valid entry
One detail can significantly change the behavior of a trading strategy:
the moment when the trade is actually entered.
Imagine an M15 strategy generates a BUY condition shortly after a new candle begins.
If the entry happens during the first 10% of the candle:
the movement may only be starting;
the entry may still be close to the original signal;
much of the candle's potential range may still be ahead;
the distance to invalidation may remain relatively small.
Now imagine taking exactly the same BUY condition when 85% of the candle has already elapsed.
The technical condition may still be true.
The moving average may still be bullish.
Momentum may still be positive.
Price may still be above the breakout level.
But the trade is no longer identical.
A large part of the current movement may already have happened.
This creates an important distinction:
Signal state ≠ entry event
A condition can remain active long after the event that originally created the opportunity.
Consider a moving-average crossover.
If the fast average crossed above the slow average 20 candles ago, the fast average may still be above the slow average today.
That tells us something about the current market state.
But it does not automatically mean that opening a new trade today is statistically equivalent to entering when the crossover happened.
The same problem exists inside a single candle.
An entry made during the first 10% of an M15 candle should not automatically be treated as equivalent to an entry made during its final 10%.
Possible differences include:
entry price;
remaining movement;
distance to invalidation;
short-term exhaustion;
available reward relative to risk;
volatility already consumed by the candle.
This is why timing deserves to be measured separately from direction.
A simple analytical framework is to divide the candle into temporal zones:
0–25% — Early
25–50% — Developing
50–75% — Late
75–100% — Very Late
These percentages are not universal trading rules.
They are measurement zones.
The more useful question is not simply:
“Is the BUY condition still true?”
It is:
“Is this still the same entry opportunity that produced the historical behavior of the strategy?”
This distinction is part of the research behind QuantMatrix.
It is also the idea behind the free QM Candle Timing Meter, a MetaTrader 5 tool designed to measure how much of the current candle has already elapsed.
The indicator does not predict direction and does not generate BUY or SELL signals.
Its purpose is simpler:
measure timing before timing becomes an unnoticed variable in the trade.
