Grid Linear Weighted Moving Average EA

See it work before you decide: load Grid Linear Weighted Moving Average EA into the MetaTrader 5 Strategy Tester, pick visual mode, and watch the grid stay completely idle until a closed candle crosses the weighted average with fresh momentum behind it.

THE NEWEST CANDLES DECIDE. OLD HISTORY DOES NOT.

A plain moving average treats a bar from three weeks ago exactly like the bar that closed a minute ago. The Linear Weighted Moving Average does not: the latest bar carries the largest weight and every older bar counts a little less, so the line bends as soon as the market really changes its mind. Grid Linear Weighted Moving Average EA uses that line to decide when a new move has begun, and then hands control to a full grid management engine that keeps shrinking the oldest exposure, one group closure and one partial slice at a time.

At a glance

• A BUY cycle can begin only when a bar closes above the LWMA after the bar before it closed at or below it; a SELL cycle needs the mirror cross below. Closed bars only, so nothing repaints.

• New in this product: the Weight Lead Guard. The LWMA must stand ahead of a plain SMA of the same length, in the direction of the trade, by a minimum number of ATR. That is direct proof that the most recent bars, not old history, are pushing price your way.

• The Cross Depth Guard is kept as well: a cross that only scratches the line is ignored as noise, and a cross that lands miles past it on one violent candle is ignored as a spike.

• A slope rule keeps every entry in step with the line: a BUY only while the LWMA rises, a SELL only while it falls.

• The LWMA is drawn on the live chart in the main window, and arrows mark every candle where a cycle was armed.

• Profits are banked by groups of the oldest and newest orders, and a heavy old order is retired in partial slices instead of waiting for a full return.

• No stop loss and no forced close-all. When a limit is reached, new levels are refused while the existing book keeps being managed.

• Hedging and netting accounts are both supported, and every limit is a visible input.

FIRST STEPS

Start on EURUSD H1 or XAUUSD D1 with the default 0.01 lot and the additive ladder. For the first session switch RunMode to Scan only: the panel then shows every plan the EA would make without sending a single order, and one button turns it to Armed when you are ready. Run the Strategy Tester on your own broker's data first, because spreads, swaps and commissions are different everywhere. On a smaller balance keep the starting lot and let the tester show you how deep the book can grow on your symbol.

Why a linear weighted average

Every average looks backwards, and every one of them is late in some way. The LWMA multiplies each closing price by its position, so with a period of 21 the newest close counts 21 times, the one before it 20 times, and the oldest just once. The result follows the present far more closely than a simple average of the same length, yet it remains a smooth line that ignores single ticks. For a grid, an early and honest start matters: a late first level means much of the move is already spent before the ladder begins.

The improvement in this release

The Weight Lead Guard is this EA's own addition. Because the LWMA leans on recent bars and the SMA gives every bar the same vote, the gap between the two lines tells you who is driving the market. When the LWMA is above the SMA, the latest bars are stronger than the average of the period; when it is below, they are weaker. On every cross the EA measures that gap, divides it by the ATR so one setting fits currencies, gold and indices, and signs it by the trade direction. A BUY needs the LWMA above the SMA by at least your minimum, a SELL needs it below by the same amount. A cross that happens while recent bars are still pulling the other way is skipped. Set the minimum to 0 to switch the guard off. The panel shows the live lead next to the depth reading, with OPEN or HOLD for each guard. Margin-level timeframe safety is included and is off by default.

One cycle, step by step

1. The read. On every closed bar the EA reads the built-in MetaTrader 5 Moving Average in linear weighted mode. The forming candle is never used, so history shows exactly what the EA saw.

2. The cross. A BUY is considered when the bar closes above the LWMA after the previous bar closed at or below it; a SELL is the mirror below.

3. The slope rule. By default the LWMA must be rising for a BUY and falling for a SELL.

4. The Cross Depth Guard. The close must sit between your minimum and maximum distance from the line, measured in ATR.

5. The Weight Lead Guard. The LWMA must lead the SMA of the same period in the trade direction by your minimum ATR fraction.

6. The optional trend filter. A slow EMA can confirm the side: trade only with it, only against it as a fade, or leave it off.

7. The rhythm. A quiet gap of bars between accepted signals keeps a choppy session from starting one cycle after another, and a signal stays valid for a few bars if a level cannot be placed at once.

8. The ladder. Levels are spaced by fixed points or by ATR, with a floor, a ceiling and an option to freeze the distance for the whole cycle. BUY and SELL grids can run side by side or in one direction only.

9. The harvest. The closer searches for groups of the oldest and newest orders and closes a group as soon as its combined result, after swap and commission, beats your target. When the oldest order is still too heavy, only a slice of it is closed, paid for with profit already on the table.

10. The safety checks. A reopen guard blocks any closure that would reopen the same level straight away. Every leg is checked against the deal history, failed legs go into a retry queue, and a plan is dropped if the book changes between the scan and the send.

11. The optional hedge cycle. Off by default. When switched on it holds a balanced pair on a symbol you choose and retires it in equal slices, paid for by a small surcharge on closures the grid is already making.

The panel

The panel sits on the left of the chart and leaves the right side and the price scale free. It shows the symbol and magic number, a status pill (ARMED, SCAN ONLY or PAUSED), grid mode, lot step, spacing, banked profit, the book in lots with its net result, the closing plan for each side with its own close button, and the order list. The LWMA PULSE row shows the period and live value of the line, whether price is above or below it, whether it is rising or falling and how many bars ago the last cross happened. The DEPTH GUARD row shows the live distance in ATR with its state, the live weight lead with its state, and the trend filter. Buttons switch Armed / Scan only, Pause / Resume, chart marks and slicing. The Hedge Vault card is docked directly under the main panel and follows it when you drag or minimise. The panel scales with the screen and draws nothing in a non-visual backtest, so optimisation stays fast.

Protection you control

No stop loss and no forced close-all. A reached limit stops new levels; it never dumps the book at a bad moment.

Before each order the money check asks one plain question: is there enough free margin, with a safety buffer, for this order?

Limits on levels per grid, orders per side and lot per order keep the ladder bounded, and the lot ladder stops growing at the level limit.

On netting accounts the margin of the merged position is capped as a percentage of equity.

Optional margin-level timeframe safety moves the signal and the spacing to a higher timeframe when the margin level falls to your chosen levels, and moves back only after margin recovers past a cushion. Off by default.

Every copy isolates itself by symbol and magic numbers, so several charts never touch each other's orders or saved state.

Scan only mode shows every decision without sending any order.

Who it suits, and who it does not

It suits traders who want one visible line on the chart as the reason for every new cycle, who like many small closures more than one distant target, and who are ready to size the lot for their own account. It does not suit anyone who needs a stop loss on every order, a promised monthly figure, or a set-and-forget robot running large lots on a tiny balance.

Quick answers

Does it repaint? No. Signals come from closed bars only.

What is the difference from an EMA? An EMA also favours recent bars, but its weights fade slowly and never fully forget the past; the LWMA uses a fixed window with a straight-line weighting, so a bar that leaves the window stops counting at all.

Can I make the line faster or slower? Yes. A shorter period reacts sooner and gives more crosses; a longer one gives fewer, calmer crosses.

Can I use it on gold or indices? Yes. It runs on any symbol and timeframe; ATR spacing and both ATR based guards adapt to the symbol.

Can I run it on several charts? Yes. Give each copy its own magic numbers and they stay fully separate.

Can I make it trade more or less often? Yes. Lower SignalBarsDelay or the guard minimums for more cycles; raise them, use a longer period, or switch on the trend filter for fewer.

Honest expectations

A grid manages a position; it cannot see the future. Grid Linear Weighted Moving Average EA is careful about when a cycle begins and works steadily to keep each cycle short and each old order shrinking, but a market can cross the line with fresh momentum and still reverse hard, keeping the book open for a long time. Choose a lot your account can carry through that, test on your own broker first, and let the Strategy Tester show you how it behaves before you trade it live. It runs on any symbol and timeframe and needs no DLLs and no extra files.

If it earns a place on your charts, a short and honest review of how it behaved on your account, good or bad, helps other traders make their choice.
