Grid Triple Exponential Average EA

Try it free before anything else: load Grid Triple Exponential Average EA into the MetaTrader 5 Strategy Tester, switch on visual mode, and watch the panel follow every level, every banked closure and every partial slice as it happens.

A grid that lets triple-smoothed momentum decide when a cycle may begin, measures its steps with the market's own volatility, and then retires the oldest exposure piece by piece instead of waiting for one big recovery.

WHY TRIPLE EXPONENTIAL AVERAGE

Most price noise disappears when you smooth it once. Some survives a second pass. Almost nothing survives three. The Triple Exponential Average, known as TRIX, is momentum that has been filtered three times, so when it turns, the turn usually means something. This EA uses that calm reading only as a door: it decides when a fresh grid cycle is allowed to start. From that moment a full management engine takes over, builds the ladder, banks small profits, slices away old positions and keeps the account breathing. The signal is read from closed bars, so what you see in the tester is what the EA saw at the time.

WHAT IS NEW IN VERSION 3.11

Magic isolation. Every piece of stored state now carries the account, the symbol, the grid magic number and the hedge magic number in its key. Two copies of the EA on two symbols, or two copies on one symbol with different magic numbers, keep completely separate memories: separate counters, separate anchors, separate retry queues. One copy can never read, overwrite or close what belongs to another. The grid only ever touches positions with its own magic, and the hedge module refuses to start if its magic equals the grid magic.

Carried over from 3.10. The redesigned on-chart panel and the reworked money check that asks a single honest question about free margin instead of rejecting valid levels on larger accounts.

ONE CYCLE, FROM START TO FINISH

1. The door opens. TRIX turns on the signal timeframe. The EA accepts a new signal only after a quiet spacing of bars since the last accepted one (30 by default), so a choppy session cannot trigger a burst of cycles. A signal stays valid for a few bars while the other conditions line up.

2. The ladder grows. A BUY grid and a SELL grid can run side by side, each with its own anchor and counter, or you can keep to one direction. Steps follow ATR with a floor and a ceiling, or a fixed point distance if you prefer. You may freeze the ATR step for the whole cycle so the spacing never drifts underneath you.

3. The harvest. The scanner studies groups made of the oldest and the newest orders on each side and closes the group as soon as the combined net result, after swap and commission, clears your target. If an old order is still too heavy to close whole, target slicing closes only a part of it, paid for by profit already sitting in newer orders. Bounce after bounce, the heaviest positions shrink.

4. The guard. A reopen guard rejects any closure that would immediately reopen the same level, the quiet habit that makes many grids feed their balance to commission. Every closure is checked against the deal history, failed legs go to a retry queue, and a plan is cancelled if the book changed between the scan and the send.

5. Optional hedge cycle. Off by default. When enabled, it holds a perfectly balanced pair on a symbol you choose and retires it in equal slices funded by a small, capped surcharge on closures the grid already makes. A timer checks that both legs stay equal and repairs a naked leg automatically.

THE PANEL

The panel sits on the chart and shows symbol and magic number, a status pill (ARMED, SCAN ONLY or PAUSED), grid mode, lot step, ATR spacing, banked profit, the book in lots and net result, the current closing plan of each side with its own close button, and the list of open orders. Buttons switch armed or scan only, pause or resume, chart marks and the slicing cutter. It can be dragged and minimised, adapts to the screen, offers an optional Arabic line under each English label, and draws nothing in a non-visual backtest so optimisation stays fast.

SAFETY THAT STAYS IN YOUR HANDS

There is no stop loss and no forced close-all; protection works by blocking new levels, never by dumping the book at the worst moment. Every limit is a visible input: maximum levels per grid, maximum orders per side, maximum lot per order, a margin-level floor, a floating-loss ceiling, a spread filter, and on netting accounts a cap on the margin of the merged position as a percent of equity. The lot ladder stops growing at the level limit, so partial closes can never push sizes beyond what you allowed. Scan Only mode shows every decision without sending a single order.

HOW TO START

Step 1: In MetaTrader 5 open Tools, Options, Expert Advisors and make sure algorithmic trading is allowed.
Step 2: Open the chart and timeframe you want to trade; EURUSD H1 or XAUUSD are comfortable first choices.
Step 3: Drag the EA from the Navigator onto the chart and tick Allow Algo Trading in the Common tab.
Step 4: In Inputs set RunMode to scan only for your first session, keep the 0.01 starting lot with the additive ladder, and leave the hedge cycle off.
Step 5: Watch the plans on the panel, then press the button to arm it when you are comfortable.
Step 6: If you run several copies, give each one its own EAMagicNumber and HedgeMagicNumber; version 3.11 keeps their states apart automatically.
Step 7: Before trading live, run the Strategy Tester on your own broker's data, because spreads, swaps and commissions differ from broker to broker.

HONEST EXPECTATIONS

A grid manages a position; it does not predict the future. This EA chooses carefully when to begin and then works to keep each cycle short and each old order shrinking. Pick a lot size your account can carry through a long trend, test on your own broker first, and let the Strategy Tester show you its rhythm before going live. It works on any symbol and timeframe and needs no DLLs or extra files.

If you use the EA and find it useful, an honest review describing your own experience helps other traders decide.
