FOLLOW THE VOLUME, THEN BUILD THE LADDER
Grid Accumulation Distribution EA starts a grid cycle only when real buying or selling pressure shows up in the Accumulation/Distribution line, then hands the trade to a disciplined ladder engine that banks small net gains and trims old exposure piece by piece.
See it before you trust it: open the MetaTrader 5 Strategy Tester, pick your symbol, tick visual mode and press Start. The A/D line appears in its own window, arrows mark every candle that armed a cycle, and the new A/D Flow row on the panel tells you, bar by bar, which side is in control. Your broker, your data, zero cost.
- Trigger: the A/D line crosses its own moving average, and its recent slope must point the same way; up means accumulation (buy), down means distribution (sell).
- Panel upgrade: an "A/D Flow" row reports BUYING or SELLING pressure, the gap to the signal average, slope, bars since the last cross and a divergence hint.
- Engine: buy and sell ladders side by side, volatility-based spacing, grouped net closures and partial slicing of the heaviest order.
- Every limit is an input you can see: lot ceiling, level ceiling, margin and drawdown blocks, spread filter, observation mode.
- Each chart keeps its own memory keyed to symbol and both magic numbers, so many instances can share one account safely.
QUICK START
- Where: EURUSD H1 and XAUUSD H1 are friendly first charts. Any instrument and any timeframe is accepted.
- What to change: nothing at first. The shipped values open 0.01, grow by 0.01 per level and never exceed 1.0 lot per order.
- How much capital: size the account so it can hold a long one-directional move at the lot you pick. Small accounts should stay at 0.01.
- First day: set RunMode to scan only, let the EA draw its plans without trading, then arm it with the panel button when you are comfortable.
- Hedge cycle: keep it switched off until the grid alone feels familiar.
WHY VOLUME FLOW IS A GOOD STARTING SIGNAL
Most grids get into trouble because their first order is placed at an arbitrary moment. Price alone can mislead: a candle may print a new high while the money behind it is quietly leaving. The Accumulation/Distribution line, created by Marc Chaikin, looks at where each bar closes inside its own range and weights that location by volume. A close near the top adds volume to the running total, a close near the bottom subtracts it. Over time the line shows whether participants are collecting a market or handing it off.
This EA smooths the A/D line with a moving average you choose and waits for the raw line to cross that average on a finished candle. A crossing on its own can be noise, so by default the line must also have risen (for a buy) or fallen (for a sell) across a short slope window. Only then does the cycle arm, after your direction permissions and the spacing between signals have been respected. Because only completed bars are read, arrows already drawn stay where they are. Tick volume is used by default so the signal works on every forex and CFD feed; real exchange volume can be selected where your broker supplies it.
NEW IN VERSION 3.12
A/D Flow on the main card. A single compact line answers the question every grid trader asks: who is pushing right now? It names BUYING or SELLING pressure, prints the distance between the A/D line and its average as a percentage of the recent A/D range, shows whether the slope is up, down or flat, counts how many bars the current side has held, and flags a bullish or bearish divergence when price and the A/D line have travelled in opposite directions over your chosen window. The data is live, read from the same indicator handles that drive the trades.
Indicator window and entry arrows. On a live chart the A/D line is attached under the price and removed cleanly when the EA stops; arrows sit on the candles that started each cycle.
Instance isolation. Saved state, retry queues and the hedge fund are stored under keys made from account, symbol and both magic numbers. At start-up a lock prevents a second chart from reusing a magic already taken, and every scan of open positions filters by symbol and its own magic.
Honest margin check. Before a level is opened the terminal computes the real margin of that order and compares it, with a safety cushion, to the free margin available. Large balances are no longer refused valid orders.
Stop-out minded defaults. The lot ceiling, level ceiling and netting margin cap ship with conservative values, so an installation left untouched stays within sensible limits.
LIFE OF A CYCLE
1. Listening. While neither side shows conviction, the EA does nothing. The A/D Flow row and the signal gate on the panel show the current pressure and how many bars remain before a new signal may count.
2. Arming. When the A/D line crosses its average with a matching slope, the EA checks your buy/sell switches and the minimum bar gap, then opens the first level and marks the candle.
3. Laddering. As price moves away from the anchor, further levels are added. Buy and sell ladders can work at the same time with separate anchors and counters, or a single side can run alone. Spacing follows ATR between a floor and a cap, or stays fixed in points.
4. Collecting. A scanner combines the oldest and newest orders of each side and closes a group as soon as its net result, after swap and commission, clears your target. When the oldest position is too heavy, only part of it is closed, paid for by profit already sitting on newer orders. Repeated swings wear the largest position down.
5. Protecting the rhythm. A reopen guard rejects closures that would immediately reopen the same level. Each closure is confirmed in deal history, failed legs are retried, and a plan is abandoned if the open positions changed between scan and send.
6. Optional hedge cycle. Disabled by default. Once enabled, it keeps a balanced pair on a symbol you choose and retires it in equal slices financed by a small surcharge on grid closures. Its purpose is trading volume; its own cost is spread, commission and swap.
THE PANEL
The panel keeps the proven card layout on the left side of the chart, leaving the price scale and right side free. The main card lists symbol and magic, a status badge, grid mode, lot step, spacing, banked result, the signal gate and the A/D Flow row. Plan cards show each side's next closure with a dedicated close button, and a table lists open orders. Buttons switch armed or scan-only mode, pause, chart marks and slicing. The panel can be moved and minimised, sizes itself to its text on any screen, and is not drawn at all during non-visual optimisation, so test runs stay fast.

EVERYDAY USE
Drop the EA on a chart, enable algo trading and check that the panel loads. Read the A/D Flow row first: SELLING with a down slope while you hold a buy ladder simply means the market is still against you, and the plan cards will show what a closure needs. Pause before events you prefer to skip, switch to scan only when you want to watch without risk, and give every chart its own pair of magic numbers; the start-up lock warns you if two charts collide.
WHAT TO REALISTICALLY EXPECT
Volume flow improves timing; it does not remove risk. A persistent trend against an open ladder can create large floating losses, and this EA has no stop loss that liquidates everything for you; its protection is to stop adding levels. Spread, swap, commission, the symbol and your lot size all shape the outcome, and tester history is no guarantee of live results. Run the free test with your own settings, begin small and increase only after you know how far your instrument usually stretches. Works on hedging and netting accounts, with no DLLs and no external files.
Once you have traded or tested Grid Accumulation Distribution EA, a review describing your genuine experience, positive or negative, would be appreciated. It helps other traders choose and guides the next improvements.
