Legoux Glidepath EA

Arnaud Legoux Moving Average grid EA for traders who want the first order placed on a line that turns early but does not twitch. One job: start a grid only when a closed bar crosses the ALMA (Arnaud Legoux and Dimitrios Kouzis-Loukas, 2009) with the main trend behind it. Mechanism: ALMA 21 / offset 0.85 / sigma 6 computed inside the EA, a Range Guard and an EMA 200, then an ATR-spaced grid that banks small closures.

Legoux Glidepath EA is an ALMA grid EA for MetaTrader 5, a Gaussian moving average expert advisor with a low-lag trend line. Why Gaussian: every one of the last 21 closes gets a weight from a bell curve, w = exp(-(i - 0.85 x 20)^2 / (2 x (21/6)^2)); the bell sits near the newest bars, so the line follows fresh price with little lag, while its smooth tails filter out single-bar noise.

Tested on: EURUSD H1, $10,000, default inputs, 2025.01.01 to 2026.09.30: net +1,514.90, maximal equity drawdown 248.61 (2.29%), 723 trades, profit factor 3.93, no stop-out, no margin refusal.

Minimum deposit: EURUSD H1 money drawdown in our test was 248.61 at the default 0.01 first lot, so start with at least $2,000; XAUUSD D1 drew down 9.43 on 10 trades, start with at least $500. These are floors from one test, not a safe zone; deposits below $10,000 were not run.

Try it free first: load Legoux Glidepath EA in the MetaTrader 5 Strategy Tester with visual mode on, default inputs, EURUSD H1. Every cross it accepts gets an arrow; on the live chart every cross a guard refuses is shown as a grey dot.

The trade lifecycle in four verbs. It weights recent closes with a Gaussian bell into one ALMA line, waits for a closed bar to cross that line with the trend behind it, opens the first level and spaces the next ones by ATR, then banks groups of orders as soon as their joint result clears the target.

Plain risk up front. This IS a grid. It adds to losing positions and uses no stop loss by default. Defaults: 0.01 first lot, additive steps of 0.01, ATR spacing with a 50 point floor, hedge cycle off, margin-level safety off. Limits stop new levels; they never force-close the book.

A LINE THAT GLIDES

A simple moving average gives every bar the same vote, so it lags. An exponential one leans on the newest bar, so it twitches. In 2009 Arnaud Legoux and Dimitrios Kouzis-Loukas proposed a third way: give the bars weights shaped like a bell curve and slide the top of the bell toward the present. The offset says where the top sits (0.85 = near the newest bar), the sigma says how sharp the bell is. The result glides close to price on a real move and stays calm through a single spiky candle, so a cross is more likely to mean price changed side.

Five things to know first

• Entry: a closed bar finishes above the ALMA line after the previous one finished at or below it (BUY), or the mirror for SELL. A slope-turn mode is included as an alternative. Accepted signals do not repaint.
• Calculated inside the EA from bar closes: window 21, offset 0.85, sigma 6. The common chart default is 9 / 0.85 / 6; we use a 21-bar window so the line suits a grid start on H1 rather than scalping. Load an ALMA with 21 / 0.85 / 6 on your chart and you will see the same line. No indicator file, no DLL, no web request.
• A Range Guard skips quiet boxes and an EMA 200 filter keeps entries on the side of the main trend. The Stretch Guard (late-entry filter) is there too, off by default.
• A new Slope Confirm is built in and ships switched OFF. We tested it on and off; it cut the drawdown hard but also halved the profit. The numbers are below, so you choose.
• No stop loss and no forced close-all. Limits stop new levels; the open book stays under management.

Start here (5 minutes)

1. Attach it to EURUSD H1 and leave every input at its default.

2. Set RunMode to Scan only for the first session. The panel shows each plan; no order is sent.

3. Look at the arrows and grey dots on the chart: they show which past ALMA crosses the guards would have taken or refused.

4. Check your balance against the minimum-deposit line above, then press ARMED on the panel.

5. Repeat the tester runs below on your own broker's data before any real money; spread, swap and commission differ between brokers. More than one chart? Give each copy its own EAMagicNumber and HedgeMagicNumber.

Reproduce our numbers

Strategy Tester, default inputs, 1 minute OHLC, 2025.01.01 to 2026.09.30, one broker's demo data (hedging account). Same settings, same period, and you should land close to these:

• EURUSD H1, $10,000: net +1,514.90, maximal equity drawdown 248.61 (2.29%), 723 trades, profit factor 3.93. No stop-out, no margin refusal.
• EURUSD H1, $1,000,000: net +1,514.90, maximal equity drawdown 248.61 (0.02%), 723 trades. No stop-out, no margin refusal.
• XAUUSD D1, $10,000: net +25.61, maximal equity drawdown 9.43 (0.09%), 10 trades, no losing closed trade. No stop-out, no margin refusal.
• XAUUSD D1, $1,000,000: net +25.61, maximal equity drawdown 9.43 (0.00%), 10 trades. No stop-out, no margin refusal.

Read these as one past stretch, not a forecast. Money drawdown is the same at both deposits because lots do not grow with the balance, so it is a far bigger share of a small account. The guards and filters were set once by judgement on this same period, which flatters them. Ten gold trades in 21 months prove nothing about gold. Netting accounts were not verified.

Slope Confirm: on or off, in numbers

The idea: a close can poke through a line that is still flat or still pointing the other way. That cross is often a whipsaw. Slope Confirm accepts a BUY only if the ALMA line is higher than it was N bars ago (SELL: lower). We tested N = 3 against off, same period, same settings:

• EURUSD H1, $10,000: off (the default), net +1,514.90, drawdown 248.61 (2.29%), 723 trades, profit factor 3.93. On, net +760.68, drawdown 87.84 (0.86%), 408 trades, profit factor 4.24.
• XAUUSD D1, $10,000: off, net +25.61, drawdown 9.43, 10 trades. On, net +18.33, drawdown 9.43, 8 trades.

What did the guard refuse? 315 of 723 EURUSD trades and 2 of 10 gold trades. On EURUSD it cut the worst drawdown by about two thirds, and profit per unit of drawdown rose from about 6.1 to about 8.7, but the total profit halved. It ships off so the default keeps the larger result; if you prefer a smoother curve and fewer trades, set InpALSlopeBars to 3 and test it on your own broker. Expect long quiet spells with it on: in a flat market the line has no slope, so crosses are refused.

Why the ALMA

A grid needs one clean starting gun, then it needs the engine to work. The ALMA is a good gun for three reasons. It is built from closes only, so it means the same on every broker. Its bell-shaped weights give it the low lag of a fast average and the calm of a slow one at the same time. And its three settings are published and easy to reproduce on any chart, so you can check every arrow yourself. The honest costs: in a sideways market price crosses any line often, and a long one-way trend holds the book open. The Range Guard, the trend filter, the signal gap and the optional Slope Confirm are there for exactly that.

One cycle, step by step

1. Weigh. On each new bar the EA weights the last 21 closes with the Gaussian bell (offset 0.85, sigma 6) and averages them into the ALMA value.

2. Cross. In the default mode a closed bar must finish on the other side of the line from the bar before it. In slope mode the line itself must turn up (BUY) or down (SELL).

3. Stretch Guard. Off by default. When set, the signal close may sit at most that many ATR from the line.

4. Slope Confirm. Off by default. When set, the line must have moved in the signal direction over the last N bars.

5. Range Guard. The last 20 bars must span at least 5 ATR, so tight boxes are skipped.

6. Trend filter. By default the close must be on the matching side of the EMA 200. It can also fade that side, or be switched off.

7. Timing. Accepted signals are kept apart by a gap of bars, and a signal may wait a few bars if the level cannot be placed at once.

8. Ladder. Levels follow ATR or fixed points, with a floor, a ceiling and an optional freeze. BUY and SELL baskets can run together or alone.

9. Banking. Groups of oldest and newest orders close when their joint result, after swap and commission, clears the target. If the oldest order is too heavy, a slice of it is closed instead.

10. Safety checks. A closure that would reopen a level at once is blocked, each leg is confirmed in deal history, failed legs are retried, and a plan is dropped if the book changed before sending.

11. Hedge cycle, optional: off by default and not exercised in our tests; when on, it holds a balanced pair on a chosen symbol and retires it in equal slices, paid by a small surcharge on closures the grid already makes.

The panel

The panel sits on the left, so the right side and the price scale stay clear. It lists symbol, magic number, a status pill, grid mode, lot step, spacing, banked result, the book, each side's closing plan and the order table. The LEGOUX ALMA row shows the settings (21, offset 0.85, sigma 6.0), whether the last closed bar sits ABOVE or BELOW the line, whether the line is rising (UP) or falling (DN), and the bars since the last cross. The ALMA GUARDS row shows the close-to-line distance in ATR (GAP) with OK, HOLD or off, the line slope for Slope Confirm (SL UP, DN or off), the Range Guard width in ATR with its state, and the EMA side. On the live chart every cross of the last 150 bars is marked: a small arrow when accepted, a grey dot when a guard refused it. Buttons switch Armed / Scan only, Pause / Resume, chart marks and slicing. The Hedge Vault card docks under the main panel; with the hedge off it stays hidden. Nothing is drawn in a non-visual backtest.

Limits you control

No setting closes the book for you; limits only stop new levels.

Each order passes a free margin check with a safety buffer before it is sent.

Caps on levels per grid, orders per side and lot per order keep the ladder finite. MinMarginLevelPercent and MaxAccountRiskPercent start at off; set them for your own account.

An optional margin-level timeframe safety moves the signal and spacing to a higher timeframe as margin falls. It is off by default and was not exercised in our tests.

Copies are kept apart by symbol and magic number.

Scan only shows every decision without sending a single order.

Who this is for

Traders who like moving-average entries but want less lag and less noise; who are happy with many small closures; who prefer an EA that trades with the main trend; and who will size lots to their balance.

Who this is NOT for

• Anyone who needs a stop loss on every order. This grid has none by design.
• Anyone expecting a fixed monthly return or a fast doubling. The tested result above is modest, and it is the honest one.
• Accounts below the minimum-deposit line above.
• Small accounts running large lots unattended. A long one-way trend can hold the book open for weeks.
• Traders who want a trade on every candle. The filters keep it quiet on purpose, and on daily gold it may wait months between entries.
• Traders who want a ready-made gold system. Gold was tested only on D1 with 10 trades.
• Traders who will not test first.

Common questions

Does it repaint? Accepted signals, chart marks and both panel rows use finished bars only.

Is it the classic ALMA? Yes: weights w(i) = exp(-(i - offset x (N - 1))^2 / (2 x (N / sigma)^2)) over the last N closes, normalised to sum to one, with N 21, offset 0.85 and sigma 6 by default.

What do offset and sigma do? Offset moves the bell: closer to 1 follows price faster, closer to 0 is smoother and slower. Sigma sets the bell's width: higher is sharper (fewer bars count), lower spreads the weight and behaves more like a plain average. Only 21 / 0.85 / 6 was backtested here.

Cross or slope mode? Cross mode waits for price to close through the line. Slope mode reacts when the line itself turns; it was not backtested here.

What did Slope Confirm refuse? 315 of 723 EURUSD trades and 2 of 10 gold trades at 3 bars. Details above.

Why does it sometimes not trade for days? The Range Guard, the EMA side and the gap between signals all wait for a clear move. That is by design.

Which markets were tested? EURUSD H1 and XAUUSD D1. Everything else is for you to test.

How much should I start with? At least $2,000 for EURUSD H1 and $500 for XAUUSD D1 at the default first lot, more if you raise the lots.

What should I change first? InpALRangeMinATR, then InpALSlopeBars, then InpALPeriod. One change at a time, and look at drawdown next to net result.

Netting accounts? A separate margin cap exists for them, but netting behaviour is unverified.

Risk, plainly

Grid trading is risky. It adds to losing positions, uses no stop loss, and a long trend can keep the book open for a long time or, with lots too big for the balance, end in a stop-out and a heavy loss. The ALMA is built from past closes and cannot see the next bar; a smoother, faster line is still not a forecast. No profit is promised. Pick lots that survive a bad run, test on your own broker, and only risk money you can afford to lose. No DLLs or extra files are needed.
