KING S1 v5.1

KING S1 v5.1 · Statistical Gold Pin-Catch Scalper (5 account licences)

KING S1 is a fully automated Expert Advisor for XAUUSD. It does not chase trends and does not predict direction. It measures the market's own short-term volatility in real time and waits for the moment price is stretched far outside its statistical range — the overshoot most likely to snap back. Entries are prepared only at those extremes, with fixed take-profits and strict time discipline.

The result is a high-frequency, short-hold strategy: the median position is closed inside a minute, so exposure to open market risk is minimal, and the equity curve is built from a large number of statistically filtered small trades rather than a handful of heavy ones.

What is new in v5.1

• Parallel entries (new, ON by default) — while positions are held, a dip that clears the full first-entry conditions opens its own independent basket instead of being forced into the deepened rescue geometry. Measured over the same period: net +$18,780 → +$22,562 (+20.1%), with absolute equity drawdown actually falling from 20.73% to 16.05%
• Basket cap + minimum entry spacing (new) — at most 2 independent baskets, and a new basket may not open within $5 of any existing entry price, so a cluster cannot stack on one level
• Drawdown stop (new, OFF by default) — closes the whole book and stops trading at a set relative equity drawdown. Shipped off; if you arm it, arm it at 35% or higher — see below
• Commission correction (new) — enter your broker's round-trip rate per lot and it is added to every profit floor, so a ticket is never released at a level that settles negative after costs
• The shipped mode is now Aggressive — v4.2 shipped in Flat. KING-S1-Flat.set is included: load it to get the old behaviour back

Free upgrade, and your licence key still works — v5.1 uses the same account-bound licensing as v4.2. Nothing to re-issue; just re-download from "My Orders".

How it works

• Volatility-referenced entry — a 30-minute rolling window continuously re-estimates the mean and standard deviation of price, and an entry is only prepared when price is stretched a deep multiple of that live standard deviation ("3-sigma pin"), so the engine self-calibrates in both quiet and violent conditions
• Bounce-confirmation fill — instead of resting a limit order at the extreme, the EA trails a buy-stop down into the dip, so the fill only happens once price has actually turned up rather than while it is still falling
• Seller-day VWAP guard — new first entries stand aside after a session that closed materially below its own VWAP (this filter cut full-period relative drawdown from 37.7% to 20.7% at roughly equal profit)
• Tiered mean-reversion harvest ladder — if a position is trapped by a deeper extension, a small, controlled ladder captures the snap-back, each layer with its own trend and spacing filters
• Profit-gated grid compression — once a realised cushion is built for the month, the engine tightens its grid, converting chop into a smoother curve
• Hot-hand continuation — after a run of fast take-profits, size steps up inside a strictly capped chain (length 2) and then falls back
• Runner-gate exit — at the old take-profit level a position locks that profit as a floor, banks half the volume at market and trails the remainder, so a genuine continuation is not cut short at +65
• Bear kill-switch — a daily-bar defence line pauses new entries through sustained downtrends while open positions keep running to their own targets

Design principle: a position never carries a losing stop. The only stop ever placed is the profit floor, which sits at or above the old take-profit. Risk control is halting new entries plus the bear kill-switch — not realising open losses.

Three modes — one switch

Measured on XAUUSD real tick data, 2025.01.02 – 2026.07.22, $1,000 deposit, 1:500 leverage, parallel entries ON, drawdown stop off.

Mode	Net	Account	Relative DD	Absolute DD	Profit factor	Trades
Flat (fixed lot)	+$2,945	3.9×	13.30%	10.60%	—	3,380
Standard (compounding)	+$8,192	9.2×	17.63%	17.33%	26.29	5,488
Aggressive (shipped default)	+$22,562	23.6×	28.63%	16.05%	25.98	6,538

Every figure comes straight from the MetaTrader 5 Strategy Tester on real tick data. Ready-made presets for Flat and Standard are in the package; Aggressive is the out-of-the-box state.

Said up front: where these numbers stop being true

• Full-period figures are not any given start date's figures. Across five rolling start dates, the worst (starting 2026-02) ran 13.7 percentage points deeper in relative drawdown. Size the deposit for that, not for the best-looking row
• The compounding modes do not scale neutrally with the deposit. Same period, same defaults, deposit as the only variable: $10,000 returns +$262,004 (11.6×) but relative drawdown reaches 35.33%, past the 30% budget this product is sized against. Materially above $1,000, pick one — set BaseCapitalUsd to 1000, switch to Standard, or arm the drawdown stop at 35%
• Flat is the genuinely deposit-independent mode. At $10,000 it takes the same 3,380 trades for the same +$2,945; the drawdown is simply 2.31% instead of 13.30%
• It has losing years. 2022 was a bad year for this engine: from $1,000 with the guard off, -$1,004 at 102% relative drawdown — the account was gone. With the guard at 25%, -$160 at 25.02%. That is the one scenario where the drawdown stop truly earns its keep
• The drawdown stop has no gentle middle. Over the same period, 35% is bit-identical to off (it never trips), 30% leaves +$2,969 and 25% leaves +$2,214 — both trip on the first deep excursion and sit flat for the remaining months. If you arm it, use 35% or higher

Past performance does not guarantee future results. Always re-run the backtest on your own broker's data before going live.

Licensing: one purchase = 5 MT5 accounts

• After payment, open "My Licenses", enter an MT5 account number, and the key for that account is issued instantly — no waiting for a human
• Use the 5 slots separately, whenever you like. Keys are bound to the account and never expire
• Submitting the same account again returns the same key and does not consume another slot
• Out of slots? Buy again for 5 more. Backtesting and optimisation need no key at all
• Without a key the EA still loads, still draws its panel and still manages any open position — only NEW entries are blocked, so an unlicensed copy can never strand a live book

Recommended setup

• Symbol XAUUSD · timeframe M1 (required) · account type Hedging (required)
• Minimum deposit $1,000. Running a compounding mode on a materially larger deposit? Read the scaling note above first
• Leverage 1:500 or higher (required) · low-spread / raw / ECN gold with fast execution · VPS strongly recommended
• After attaching, set CommissionPerLotUsd to your broker's round-trip rate per lot, or the exit targets are wrong

Leverage note: the strategy is calibrated at 1:500. On lower-leverage accounts the EA shrinks its lots pro rata to keep the margin footprint identical (the same period on $10,000 at 1:100 returned +$7,786 at 4.81% relative drawdown), but to reproduce the published figures use 1:500 or higher. Check your account leverage before running.

What is included

• KING-S1-BIZ-5.10.ex5 — the EA (three modes behind one switch)
• KING-S1-Standard.set — ready-made preset for the Standard compounding ladder
• KING-S1-Flat.set — ready-made preset for fixed-lot mode (v4.2's shipped behaviour)
• README.txt — upgrade notes, installation, attaching, parameter-by-parameter reference, deposit guidance and troubleshooting (English and Chinese)

Risk warning

Trading leveraged instruments carries a high level of risk and can result in the loss of all your capital. Only trade with money you can afford to lose, and validate the EA on a demo account under your own broker's conditions first. Nothing on this page is investment advice.
