Open Letter to Matthew Klein from an Investor Group

I define a successful strategy as one that:

  1. No Grid trading
  2. No Martingale trading
  3. No Arbitrage trading
  4. No adding to losing trades
  5. Max risk per trade: 1–2%
  6. Max DD: 10–20%
  7. Generates consistent gains over a minimum six-month

How do you define a successful strategy?

Around the same, but allow drawdown up to 30% and consistent returns thru all strategy life, not only 6 months. Also prefer when annual return to drawdown ratio is around 2, but more is better.

I will immediately cease trading this strategy if the maximum drawdown hits 20%.

Consider this your ultimate safety mechanism. Exceeding this threshold signals that the advantage has expired or the market has fundamentally changed. Stop, readjust, and prioritize survival.

We operate in an increasingly volatile global landscape where the future is inherently unpredictable. Consequently, a strategy’s true value is measured not by its peak performance in calm waters, but by its resilience in the face of geopolitical shocks and systemic crises.

Crisis endurance is the ultimate litmus test; any strategy that thrives solely in tranquil conditions is a facade. True potential is defined by a capacity to withstand turbulence such as the ongoing instability in the Middle East and still deliver consistent alpha. If a strategy falters under geopolitical pressure, incurring heavy drawdowns, it is fundamentally unreliable, regardless of how impressive its historical track record may appear during stable periods.
