Where Flex is ahead

It has years of real accounts and Kestrel has none. That is the whole of it, and no simulated number cancels it out. A vendor who leaves nine accounts public, including the ones that fell 85 per cent, is showing more than most.

The range is also informative in a way a single number is not: the same expert advisor produced a 25.8% drawdown on one setting and 85.0% on another, which tells a buyer that the settings, not the software, decide the risk.

Where Kestrel is ahead

An account that falls 85% below its peak needs roughly seven times the capital of one that falls 12% to end the same episode in the same place. That is the cost of the drawdown column, and it is rarely priced into these comparisons.

Kestrel publishes the worst case and the account size it assumes together, per portfolio and level; there is no high-risk variant to choose, because every configuration is measured before it is sold. EURUSD Patient’s deepest fall from an equity peak is €2,788, which is 32.8% of the €8,500 that record recommends (2010 to September 2026, simulated); measured against the equity peak itself — the criterion Myfxbook uses — the percentage is smaller, because by then the peak sits well above the starting capital. Either way it is a simulation, so it belongs in a different column, not a better one.

The floating loss is the number that decides whether an account survives, because this family of strategies never closes a basket at a loss; it waits. Kestrel floated −€2,788 on EURUSD Patient on 21 August 2024, its worst instant in sixteen simulated years and 32.8% of the €8,500 that portfolio recommends.

What you choose with Kestrel

Your pairs — 1 to 4 of EURUSD, GBPUSD, EURCAD and AUDCAD — then Patient, Active or both for each (Patient adds to a basket less often and holds a smaller worst case; Active adds more often, returned more in the backtest and reached a larger worst case); and the level whose recommended capital fits your account: Horizon €999, Summit €4,999 or Zenith €9,999 per year, VAT included. Like the kestrel that hangs still in the wind, the design holds one measured position instead of chasing every move.
