Consistency is what compounds.

A quantitative method sets the entry, the exit, and the risk by the same rules every time — so the returns and the drawdowns can be measured, not hoped for.

Questions worth asking

How do you distinguish durable edge from an overfit backtest?

A strategy must work beyond the data used to develop it. We test unseen periods, randomized in-sample and out-of-sample quarters from every year, rolling walk-forward windows, multiple-testing penalties, and year-by-year consistency. A strong full-period return cannot rescue a strategy that fails those checks.

What assumptions are included in the published results?

The simulation starts with $500,000. Risk is sized as a percentage of simulated equity, so position sizing compounds; trades that exceed the capital constraint are skipped. It includes modeled trading costs and bar-by-bar execution. It remains hypothetical: latency, partial fills, short availability, taxes, and operational errors can make live results worse.

How should I read the return alongside the drawdown?

Never in isolation. Maximum drawdown is the worst historical peak-to-trough decline, not a limit on future loss. We evaluate return relative to drawdown, losing periods, annual consistency, and tail behavior rather than optimizing the headline return alone.

What changes when a strategy moves from simulation to live trading?

The rules stay fixed; execution becomes the test. We compare signal timing, fills, slippage, rejected orders, exposure, and realized drawdown with the simulated range. Live and simulated records remain separately labeled so one cannot be mistaken for the other.

What happens when an edge weakens?

One losing month is not enough to rewrite a system. We monitor sustained changes in expectancy, drawdown, execution quality, and market participation against predefined ranges. Persistent deterioration leads to lower risk or retirement—not a quiet refit of the historical record.

Are product fees included in the performance shown?

No. The chart is net of modeled trading costs, not access fees. Signals membership is $189 per month plus applicable tax and renews until canceled. The research platform and private management are coming soon; their pricing has not been finalized.

How do account size, liquidity, and client control affect the result?

Returns do not scale perfectly. Position limits, buying power, spreads, and available liquidity determine practical capacity for each strategy. Clients keep control of their own account and capital; research, signals, and software do not require us to custody funds or brokerage credentials.
