Grid Rate of Change EA

- アクティベーション: 5
Built for grid traders who want the market to prove its speed before the first order. One job: open a grid only when momentum flips with real force and the trend agrees. Mechanism: a Rate of Change zero cross on a closed bar, checked by a Thrust Guard, a Range Guard and an EMA 200, then an ATR-spaced grid that banks small closures.
Tested on: EURUSD H1, $10,000, default inputs, 2025.01.01 to 2026.09.30: net +724.46, maximal equity drawdown 239.08 (2.31%), 335 trades, no stop-out, no margin refusal. Deepest basket: 8 grid orders open at the same moment, 0.60 lots in total.
Try it free first: load Grid Rate of Change EA in the MetaTrader 5 Strategy Tester with visual mode on, default inputs, EURUSD H1. Every crossing it accepts gets an arrow; every crossing a guard refuses is shown on the live chart as a grey dot.
The trade lifecycle in four verbs. It measures how far price has travelled over the last 12 finished bars, waits until that speed flips from negative to positive (or back) with a real jump and the trend behind it, opens the first level and spaces the next ones by ATR, and 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.
----------
SPEED BEFORE SIZE
Rate of Change is one of the oldest momentum tools in technical analysis, and one of the simplest: the percent difference between the close now and the close a fixed number of bars ago. Above zero, price is higher than it was 12 bars back, so the recent push belongs to buyers. Below zero, to sellers. When it crosses zero, the direction of travel has changed. The EA adds a 9 bar EMA of the ROC as a signal line for an optional faster mode.
Five things to know first
• Entry: ROC crosses above zero (BUY) or below zero (SELL) on a closed bar. A signal-line mode is included for earlier, more frequent entries. Accepted signals do not repaint.
• Calculated inside the EA from closing prices. No indicator file, no DLL, no web request.
• The new Thrust Guard asks for a real jump on the crossing bar, a Range Guard skips quiet boxes, and an EMA 200 filter keeps entries on the side of the main trend.
• The Thrust Guard ships switched ON at 1.5, because in our test it cut the worst drawdown by 70% and earned more per unit of drawdown. The full on/off numbers are below, including where it did worse.
• 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 crossings the guards would have taken or refused.
4. When the plans make sense to you, 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, leverage 1:100, 2025.01.01 to 2026.09.30, one broker's demo data. Same settings, same period, and you should land close to these:
• EURUSD H1, $10,000: net +724.46, maximal equity drawdown 239.08 (2.31%), 335 trades, deepest basket 8 orders / 0.60 lots. No stop-out, no margin refusal.
• EURUSD H1, $1,000,000: net +724.46, maximal equity drawdown 239.08 (0.02%), 335 trades, deepest basket 8 orders / 0.60 lots. No stop-out, no margin refusal.
• XAUUSD D1, $10,000: net +19.42, maximal equity drawdown 32.01 (0.32%), 6 trades, deepest basket 1 order / 0.01 lots. No stop-out, no margin refusal.
• XAUUSD D1, $1,000,000: net +19.42, maximal equity drawdown 32.01 (0.00%), 6 trades, deepest basket 1 order / 0.01 lots. No stop-out, no margin refusal.
Read these as one past stretch, not a forecast. The deepest basket is counted from the tester's deal list (largest number of grid orders open together, and their lots). 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; deposits below $10,000 were not tested. Defaults were set once by judgement on this same period, which flatters them. Six gold trades in 21 months is far too few to judge gold. Netting accounts were not verified.
----------
The Thrust Guard: on or off, in numbers
The idea: a crossing that happens because ROC slowly drifts over zero says less than one where it jumps. So the ROC change on the crossing bar must be at least InpROCThrustMin times the average ROC change of the 20 bars before it. Same period, same settings, guard at 1.5 against guard off:
• EURUSD H1, $10,000: on, net +724.46, drawdown 239.08 (2.31%), 335 trades, deepest 8 orders / 0.60 lots. Off, net +1,772.06, drawdown 796.76 (7.93%), 667 trades, deepest 12 orders / 0.95 lots.
• XAUUSD D1, $10,000: on, net +19.42, drawdown 32.01, 6 trades. Off, net +28.47, drawdown 32.01, 9 trades.
On EURUSD the guard cut the worst drawdown by 70% and raised profit per unit of drawdown from about 2.2 to about 3.0, at the cost of 59% of the profit. On gold it removed three trades and some profit without lowering the drawdown, so there it was simply worse. Taken together, profit per unit of drawdown rose from about 2.2 to about 2.7, which is why it ships on. If you prefer the bigger profit and accept roughly three times the drawdown, set InpROCThrustMin to 0.
----------
Why Rate of Change
A grid needs one clean starting gun, then it needs the engine to work. ROC is a good gun for three reasons. It is pure price, so it means the same on every broker. It is in percent, so its zero line works on any symbol without retuning. And the zero cross is a single, unambiguous event on a closed bar. The honest costs: ROC compares with one past bar only, so a big candle leaving the 12 bar window can flip it on its own (the Thrust Guard and the Range Guard reduce that), it arrives after the turn has started, and in a flat market it can hover around zero. The guards, the trend filter and the signal gap are there for exactly that.
----------
One cycle, step by step
1. Measure. Each new bar recomputes ROC 12 on finished bars and its 9 bar signal EMA.
2. Cross. In the default mode ROC must cross zero, upward for a BUY, downward for a SELL. In signal mode it must cross its signal line instead.
3. Thrust Guard. The ROC change on the crossing bar must be at least 1.5 times its 20 bar average (0 switches it off).
4. Range Guard. The last 20 bars must span at least 5 ATR, so tight boxes are skipped.
5. 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.
6. 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.
7. Ladder. Levels follow ATR or fixed points, with a floor, a ceiling and an optional freeze. BUY and SELL grids can run together or alone.
8. 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.
9. 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.
10. 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 ROC PULSE row shows the period and signal length, the ROC and signal values of the last closed bar in percent, whether ROC is rising (UP) or falling (DN), and the bars since the last crossing. The THRUST GUARD row shows the side ROC favours, the mode, the bar's thrust ratio with OPEN, HOLD or off, the Range Guard width in ATR with its state, and the EMA side. On the live chart every crossing 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 want a grid that starts when momentum flips with force, not on a slow drift; who are happy with many small closures; who prefer a quiet EA that trades less with the trend behind it; 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.
• Small accounts running large lots unattended. A long one-way trend can hold the book open for weeks.
• Traders who want to trade every candle. The filters keep it quiet on purpose, and on daily gold it may sit idle for months.
• Traders who want the largest possible profit at any drawdown. The default favours a smaller drawdown; switching the Thrust Guard off trades more and swings harder.
• Traders who want a ready-made gold system. Gold was tested only on D1 with six trades, which proves nothing either way.
• Traders who will not test first. If you skip the Strategy Tester on your own broker, this is not the right tool for you.
----------
Common questions
Does it repaint? Accepted signals, chart marks and both panel rows use finished bars only.
Is it the classic ROC? Yes: 100 x (close now minus close n bars ago) / close n bars ago, with n = 12 by default. The signal line is a 9 bar EMA of it, added by this EA.
Zero or signal-line mode? Zero mode waits for the direction of travel itself to change and trades less. Signal-line mode reacts to ROC turning and trades more often; it was not backtested here.
Which markets were tested? EURUSD H1 and XAUUSD D1. Everything else is for you to test.
How deep did the grid go in the test? At most 8 orders open together on EURUSD, 0.60 lots in total, with the default guard. With the guard off it reached 12 orders and 0.95 lots.
What should I change first? InpROCThrustMin, then InpROCRangeMinATR, then InpROCPeriod. One change at a time, and look at drawdown and basket depth 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. Rate of Change is built from past closes and cannot see the next bar. 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.
If you have run it, an honest review of how it behaved for you, good or bad, helps the next trader decide.
