EudoraAntaeus — S&P 500 / US500 Index EA for MetaTrader 5

A MetaTrader 5 expert advisor for the S&P 500 index (.US500Cash) on H4, with calibrated profiles for the Nasdaq (.USTECHCash) and Dow (.US30Cash). It is a controlled-martingale recovery grid that arms a long basket only while the daily trend is up, scales in along ATR-spaced levels on a pullback, and harvests the whole basket on the bounce.

Yes. It is a leveraged controlled-martingale recovery grid: it opens multiple positions and increases size as price moves against the basket (1.5^level, up to 12 levels). This can produce large drawdowns and large or total loss of the account, including in a single adverse gap. The Showcase drawdown (~59%) is intrinsic and accrues while baskets are held; a forward, causal crash-shield pauses on extreme conditions but cannot lower it. It depends on the post-2009 up-drift and V-shaped recoveries. Trade only with risk capital — no profit is guaranteed.

On .US500Cash H4, Model=4 real ticks, RoboForex-ECN, 2018→2026, $10,000 start: Steady 4.11× (PF 1.58, eqDD ~24.5%); Balanced (recommended) 13.17× (PF 1.66, eqDD ~51%); Showcase 28.69× (PF 1.77, eqDD ~59.3%). Returns are concentrated in a few bounce days; removing the best ~5% of days reduces the Showcase result to roughly break-even. Backtests — past or simulated performance does not indicate future results.

Launch $99 for the first ~10 operators, then $149 standard; or rent for $30/month and run the engine on your own terminal first. Purchase and rental happen on the MQL5 Market; the linked MQL5 Signal runs on the conservative configuration as the live track record.

Mechanism & profiles. A leveraged controlled-martingale recovery grid for the S&P 500 (.US500Cash), with calibrated profiles for the Nasdaq (.USTECHCash) and Dow (.US30Cash). New baskets are armed only when the daily trend is up (D1 close ≥ D1 SMA50 — the load-bearing anti-ruin gate). It arms a long basket on a pullback inside that up-trend, adds a deeper level each time price falls another StepATR × ATR(14, H4) up to MaxLevels (max 12), with lot per level = LotPct × equity × 1.5^level, and closes the whole basket at average-entry + TPstep × step. A forward, causal crash-shield closes and pauses if the 10-day return is below −10%, OR D1-ATR / price > 4.5%, OR price is more than 40% below its 50-day high; it resumes after 4 H4 bars. The basket-cap (0.95 × balance) is a price level, not a guaranteed fill. Validation: MT5 real ticks (Model=4), RoboForex-ECN, .US500Cash H4, 2018-01-01 → 2026-06-01, $10,000 start — backtest results, not live trading.

Profile table (backtest, Model=4). Steady (internal label Defensive): 4.11× · equity DD ~24.5% · PF 1.58. Balanced (recommended): 13.17× · equity DD ~51% · PF 1.66. Showcase: 28.69× · equity DD ~59.3% · PF 1.77. Showcase-Extreme (band-ceiling reference, not for live deployment): 40.45× · drawdown at or above the Showcase ~59.3% level · PF 1.83.

Mandatory risk disclosure. This is a leveraged controlled-martingale recovery grid; by design it opens multiple positions and increases position size as price moves against the basket (1.5^level, up to 12 levels). This mechanism is capable of producing large drawdowns and large or total loss of the account, including in a single adverse gap or a sustained adverse market. The drawdown shown on Showcase (~59.3%) is intrinsic to the strategy and accrues while baskets are held to the bounce; the crash-shield cannot lower it. Returns are concentrated in a few bounce days; removing the best ~5% of days reduces the Showcase result to roughly break-even. Leverage is calibrated per index, and applying one index's settings to a higher-volatility index can cause large losses. The strategy depends on the post-2009 S&P up-drift and V-shaped recoveries, and a sustained no-recovery bear market would degrade it. All performance figures are MT5 Strategy Tester results (real ticks, Model=4) over 2018–2026 on .US500Cash and are backtest results, not live trading and not a forecast. Past or simulated performance does not guarantee, indicate or imply future results. No profit is guaranteed.
