ONE BIG CANDLE IS NOT MOMENTUM.
Tushar Chande built his Momentum Oscillator to weigh every rise against every fall over a window of closes. It is honest arithmetic, with one blind spot: it adds up sizes, so a single news candle can push it through a level while the other bars did very little. Grid Chande Momentum Oscillator EA starts a grid cycle only when momentum has been earned on closed bars, by several candles and not by one. From there a full management engine reduces the oldest exposure through group closures and partial slices.

At a glance
• A cycle can begin only when CMO crosses your level on a closed bar. Closed bars only, so accepted signals do not repaint.
• CMO is calculated inside the EA from the chart's own closes. No custom indicator file and no DLL.
• New in this product: the Spike Guard. It measures how much of the winning sum came from the single biggest candle and refuses the crossing when that share is too high.
• The Climb Guard asks that CMO really rose over the last few bars, rather than drifting across the line.
• The Range Guard skips crossings inside a tight box, and the default EMA 200 filter accepts only the side of the slow trend.
• On the live chart, past crossings are marked on their candles: a small arrow when one passed every rule, a grey dot when a guard refused it.
• Profits are banked by groups of the oldest and newest orders, and a heavy old order is retired in partial slices.
• No stop loss and no forced close-all. A reached limit refuses new levels while the existing book keeps being managed.

Start here
Begin on EURUSD H1 with the default 0.01 lot and the additive ladder. Set RunMode to Scan only for the first session: the panel shows each plan and no order is sent, and one button moves it to Armed when you are ready. Before going live, repeat the tests below on your own broker's data, because spreads, swaps and commissions differ.
----------
What our tests showed
Default settings, Strategy Tester, 1 minute OHLC model, 1:100 leverage, 2025.01.01 to 2026.09.30, one broker's demo data. You can reproduce the method with these exact settings:
• EURUSD H1, $10,000 deposit: net result +951.03, maximal equity drawdown 804.04 (8.03%), 310 trades, no stop-out and no margin refusals.
• EURUSD H1, $1,000,000 deposit: net result +951.03, maximal equity drawdown 804.04 (0.08%), 310 trades, no stop-out and no margin refusals.
• XAUUSD D1, $10,000 deposit: net result +47.97, maximal equity drawdown 47.92 (0.48%), 12 trades, no stop-out and no margin refusals.
• XAUUSD D1, $1,000,000 deposit: net result +47.97, maximal equity drawdown 47.92 (0.00%), 12 trades, no stop-out and no margin refusals.
Read these as simulations of one past period, not as a forecast. Notice that the drawdown in money was the same at both deposits, because the lots do not grow with the balance: 804.04 is about 8% of $10,000, and it would be a far larger part of a small account. Smaller deposits were not tested, so test your own before trusting it. The 12 XAUUSD trades are too few to prove anything. Netting behaviour has not been verified, and the account mode of these runs is not confirmed, so treat your own account type as untested until you have run it.
----------
Why CMO, and why these guards
Many momentum tools smooth their data twice and blur what happened. CMO keeps the rises and the falls side by side: their difference divided by their total, on a scale from -100 to +100. That makes it direct, and it also makes it easy to fool, because one large close change can outweigh many small ones.
The improvement in this release
The Spike Guard is this EA's own addition. On the signal bar it finds the biggest single close change on the winning side and works out its percentage of that side's whole sum. If that share is above your maximum, the crossing is refused, however high CMO reads. The panel shows the share live with OPEN or HOLD, so the decision is visible. Setting the maximum to 100 turns it off. How much this guard alone changes results has not been measured separately, and you can compare it yourself in the tester with it on and off. Margin-level timeframe safety is included and is off by default.
----------
One cycle, step by step
1. The sums. On each new bar the EA rebuilds CMO from closed bars. The forming candle is not used by default.
2. The crossing. CMO must pass through your level on the signal bar: upward through plus the level for BUY, downward through minus the level for SELL.
3. The Climb Guard. CMO must have gained enough over the last few bars.
4. The Spike Guard. No single candle may hold too large a share of the winning sum.
5. The Range Guard. The width of the CMO window, measured in ATR, must reach your minimum.
6. The trend filter. By default a slow EMA must agree with the side. You can also fade it, or switch it off.
7. The rhythm. A quiet gap of bars separates accepted signals, 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, an upper limit and an option to freeze the distance. BUY and SELL grids can run together or in one direction only.
9. The harvest. The closer searches for groups of the oldest and newest orders and closes a group once its combined result, after swap and commission, beats your target. If the oldest order is still too heavy, only a slice of it is closed.
10. The safety checks. A reopen guard blocks a 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 before sending.
11. The optional hedge cycle. Off by default, and not exercised in the tests above. When switched on it holds a balanced pair on a symbol you choose and retires it in equal slices, funded by a small surcharge on closures the grid is already making.
----------
The panel
The panel sits on the left and keeps the right side and the price scale clear. It shows the symbol and magic number, a status pill, grid mode, lot step, spacing, banked result, the book, the closing plan for each side and the order list. The CMO PULSE row shows the period, the CMO of the last closed bar and the bar before it, your level, and how many bars ago the last crossing happened. The SPIKE GUARD row shows the favoured side, the peak candle share, the climb and the window width in ATR, each with OPEN or HOLD, then the EMA side. Buttons switch Armed / Scan only, Pause / Resume, chart marks and slicing. The Hedge Vault card is built to dock under the main panel; it was not on screen in our screenshot because the hedge is off by default. The panel draws nothing in a non-visual backtest.
----------
Protection you control
No stop loss and no forced close-all. A reached limit stops new levels; it never dumps the book.
Before each order the money check asks whether there is 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. MinMarginLevelPercent and MaxAccountRiskPercent are off by default; consider setting them for your account.
Optional margin-level timeframe safety moves the signal and the spacing to a higher timeframe when the margin level falls to your chosen levels. Off by default and not exercised in the tests above.
Each copy filters by symbol and magic numbers, so give every chart its own magic numbers.
Scan only mode shows every decision without sending any order.
----------
Who it suits, and who it does not
It suits patient traders who want momentum proved by more than one candle, who prefer many small closures to one distant target, and who will 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? Accepted signals use closed bars only. The chart marks and both panel rows also read closed bars.
Which timeframes were tested? EURUSD H1 and XAUUSD D1 only. Everything else is yours to test.
Which setting should I change first? The cross level and the Spike Guard maximum. Change one at a time and compare the drawdown as well as the net result.
Can I change the CMO period? Yes. A shorter period usually gives more crossings. The Range Guard uses the same window, so review it too.
Does it work on netting accounts? The EA has a separate margin cap for them, but we have not verified netting behaviour.

Honest expectations
A grid carries real risk. It adds to positions while the market moves against them, there is no stop loss, and a long one-way move can hold the book open for a long time or, with too large a lot for the balance, lead to a stop-out and heavy loss. Strong momentum can reverse on the very next bar, because CMO describes what has happened and not what comes next. No result is promised. Pick a lot your account can carry through a bad run, test on your own broker first, and trade live only what you can afford to lose. It needs no DLLs and no extra files.
If you try it, a short and honest review of how it behaved on your account, good or bad, helps other traders make their choice.
