Capital Floor

Capital floor matters because retail EA marketing systematically understates the realistic capital required for deployment. The buyer-facing experience ("trade with as little as $100") collides with the deployment reality (positions don't size meaningfully below $1,000, drawdown bands feel catastrophic at $500 even if percentage-equivalent at $5,000).

Factors that determine capital floor:

• **Position-sizing resolution**: standard retail forex sizes start at 0.01 lots (micro-lot). At 0.5% risk-per-trade on a 20-pip-stop trade, that translates to roughly $1,000 minimum capital before position sizing becomes meaningfully scalable. Below that, sizing is binary (one micro-lot or none) and the EA's intended risk envelope breaks • **Drawdown psychological tolerance**: 25% drawdown on $500 capital ($125 loss) feels different than 25% drawdown on $5,000 capital ($1,250 loss). Many traders disable EAs at the bottom of drawdown cycles because the absolute dollar loss exceeds their psychological tolerance, even when the percentage is consistent with the strategy's normal behaviour • **Margin pressure during drawdown**: when capital drops 30% during stress, broker margin requirements eat into the remaining capital. Below capital floor, this margin pressure makes the EA unable to maintain normal position sizing during exactly the period when it most needs to • **Commission consumption**: at low capital, fixed commissions per lot consume meaningful fraction of returns. A $3/lot commission on a strategy generating $5/lot net consumes 60% of edge at small scale; the same commission consumes <1% at institutional scale • **Multi-pair sizing**: multi-pair EAs need enough capital to deploy meaningful positions across all pairs simultaneously; otherwise the per-pair sizing becomes coarse and the diversification benefit disappears

Editorial capital floors by EA tier:

• **Beginner tier**: $500 absolute floor (Fortuna EA), $1,000 recommended for diversification (Trendopedia) • **Safety tier**: $1,000-$2,000 minimum; $5,000 recommended for multi-pair architectures • **Most-profitable tier**: $2,000-$3,000 minimum; $10,000+ recommended for the strategies' intended risk profile • **Professional tier**: $15,000-$25,000 minimum; $50,000+ recommended for multi-strategy ensemble architectures

For EA buyer evaluation: vendors publishing honest capital floors signal serious engineering thinking; vendors advertising "any account size" while having strategies requiring substantial capital signal marketing-driven product positioning. Confirm the vendor's published capital floor matches the verified live deployment's account size; significant mismatch (vendor advertises $500 floor but verifies on $25,000 account) indicates the strategy doesn't actually operate as advertised on small accounts.
