Desarrollador de sistemas automatizados de trading en FX enfocado en estrategias robustas y basadas en reglas.

Mi trabajo se centra en sistemas automatizados basados en rangos y conscientes del régimen de mercado, diseñados con énfasis en la preservación de capital, la consistencia estadística y la supervivencia a largo plazo en condiciones reales de mercado.

Priorizo la ejecución selectiva, la exposición al riesgo controlada y un diseño conservador por encima de enfoques agresivos o de alta frecuencia. Todos los sistemas se construyen utilizando lógica transparente, filtros de seguridad estrictos y una extensa evaluación histórica a través de distintos regímenes de mercado.

El soporte, la claridad y el perfeccionamiento continuo son principios fundamentales detrás de cada lanzamiento.

What Does a Small Edge Actually Look Like?

I ran 1,000 Monte Carlo simulations for two simple systems:

System A

R:R = 1:1

Win rate = 50%

No edge

System B

R:R = 1:1

Win rate = 55%

Positive edge

Each simulation:

1,000 trades

Fixed risk per trade

Initial capital: $10,000

What happens?

Breakeven system:

Final balance distribution centers around initial capital

Outcomes are purely variance-driven

Positive edge system:

Entire distribution shifts to the right

Median outcome increases materially

But dispersion remains high

Even with a real edge, not every path wins.

Conclusion

Edge does not eliminate volatility.
It shifts probability mass.

Trade by trade, the difference looks small.
Across 1,000 trades, the distribution changes completely.

Expected value determines direction.
Variance determines experience.

Sharpe Does Not Eliminate Path Risk

A systematic strategy showing:

Sharpe Ratio: 2.02

CAGR: 69.5%

Max Drawdown (realized): −15.6%

1,059 trades

Expectancy: 0.13R

From a classical perspective, this is statistically robust.

However, Sharpe measures return efficiency relative to volatility.
It does not measure sequencing risk.

What Happens If We Reshuffle the Same Trades?

I ran a bootstrap Monte Carlo simulation:

1,000 reshuffled trade sequences

Fixed 1% risk per trade

Initial capital: $50,000

No parameter changes

Same edge, same expectancy

Only trade order randomized

Results

Final Balance Distribution:

Mean: $197,755

Median: $182,512

5th percentile: $97,235

Probability of finishing below initial capital: 0.2%

The statistical edge clearly shifts the distribution to the right.

Drawdown Behavior Under Reordering

Drawdowns across simulations:

Mean max DD: 18.7%

95th percentile max DD: 28.3%

Extreme worst case observed: 40.2%

The historical max DD was −15.6%.

Most alternative paths remain within a statistically reasonable drawdown range.
Occasional deeper drawdowns are structurally possible due to trade clustering.

Same edge.
Different paths.

Takeaway

Sharpe summarizes the realized trajectory.
It does not describe the full distribution of plausible outcomes.

Performance should be evaluated as a probability distribution — not a single equity curve.

Development update — capital management refinement in progress.

Current research is focused on implementing a new capital management framework designed to preserve balance stability while selectively exploiting performance peaks.
The objective is to maximize long-term returns without increasing overall market exposure, maintaining the system’s conservative and regime-aware philosophy.

This work is part of the ongoing effort to strengthen robustness, improve survivability in live conditions, and enhance risk-adjusted performance over time.
