Built for grid traders who want volume, not just price, to give the starting signal. One job: open a grid only when money flow turns with the trend. Mechanism: a Klinger Volume Oscillator zero cross, confirmed by range 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 +1,094.29, maximal equity drawdown 244.92 (2.31%), 515 trades, no stop-out, no margin refusal.
Try it free first: load Grid Klinger Oscillator 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 weighs the volume behind each finished candle, waits until the volume flow swings to the other side of zero with 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.
----------
FOLLOW THE VOLUME
Price can drift on thin trading; real turns usually come with volume. The Klinger Volume Oscillator turns that idea into one line. For each finished bar the EA checks whether the typical price (high + low + close) rose or fell against the bar before, and signs that bar's tick volume plus or minus. That signed volume is the volume force. A fast 34 bar EMA of it minus a slow 55 bar EMA gives the oscillator, and a 13 bar EMA of the oscillator gives the trigger line. Above zero, volume has been leaning toward buyers lately; below zero, toward sellers. When it crosses zero, the flow has changed sides.
Five things to know first
• Entry: the oscillator crosses above zero (BUY) or below zero (SELL) on a closed bar. A trigger-line mode is included for earlier, more frequent entries. Accepted signals do not repaint.
• Calculated inside the EA from high, low, close and tick volume. No indicator file, no DLL, no web request.
• A Range Guard skips quiet boxes and an EMA 200 filter keeps entries on the side of the main trend.
• New in this product: the Volume Guard, which can refuse a crossing printed on a thin, quiet bar. It ships switched off, and the measured reason is printed below.
• 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, commission and even tick volume 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 +1,094.29, maximal equity drawdown 244.92 (2.31%), 515 trades. No stop-out, no margin refusal.
• EURUSD H1, $1,000,000: net +1,094.29, maximal equity drawdown 244.92 (0.02%), 515 trades. No stop-out, no margin refusal.
• XAUUSD D1, $10,000: net +18.21, maximal equity drawdown 7.71 (0.08%), 5 trades. No stop-out, no margin refusal.
• XAUUSD D1, $1,000,000: net +18.21, maximal equity drawdown 7.71 (0.00%), 5 trades. No stop-out, no margin refusal.
Read these as one past stretch, not a forecast. 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. Five gold trades in 21 months is far too few to judge gold. Tick volume is the broker's count of price changes, not exchange volume, so results can move from one broker to another. Netting accounts were not verified.
----------
The Volume Guard and why it ships off
The idea: a crossing on a bar with little activity carries less weight, so the event bar's tick volume could be required to reach InpKVOVolMin times the average of the 20 bars before it. We tested it at 1.2 with everything else at default. EURUSD H1, $10,000: on, net +590.44, drawdown 180.73 (1.73%), 309 trades; off, net +1,094.29, drawdown 244.92 (2.31%), 515 trades. XAUUSD D1, $10,000: on, no trade at all in 21 months; off, +18.21 from 5 trades. It did lower the worst drawdown by 64.19, but it cut the profit by 46%, so profit per unit of drawdown fell from about 4.5 to about 3.3, and it silenced gold completely. Calmer, but not safer per dollar earned, so it ships off (0). If a smaller drawdown matters more to you than the profit, try values from 1.0 to 1.5 on your own symbol.

Why the Klinger oscillator
A grid needs one clean starting gun, then it needs the engine to work. The Klinger oscillator is a good gun for three reasons. It mixes participation with direction, so a slow drift on thin trading moves it less than a push with real activity behind it. Its two long averages (34 and 55) ignore single noisy bars. And the zero cross is a single, unambiguous event on a closed bar. The honest costs: long averages arrive after the flow has already turned, the oscillator's size depends on the symbol and broker's volume (so it has no fixed levels), and in a flat market it can hover around zero. The Range Guard, the trend filter and the signal gap are there for exactly that.
----------
One cycle, step by step
1. Weigh. Each new bar recomputes the volume force on finished bars, the 34 and 55 bar EMAs and the 13 bar trigger.
2. Cross. In the default mode the oscillator must cross zero, upward for a BUY, downward for a SELL. In trigger mode it must cross its trigger line instead.
3. Volume Guard, optional. The event bar's tick volume must be at least InpKVOVolMin times its 20 bar average.
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 KVO PULSE row shows the fast and slow lengths, the oscillator and trigger values of the last closed bar (large values shortened to k or M), whether the oscillator is rising (UP) or falling (DN), and the bars since the last crossing. The VOLUME GUARD row shows the side the oscillator favours, the mode, the bar's volume 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 volume flow changes sides, not on a single candle; 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 expect exchange volume. MetaTrader 5 forex and CFD symbols give tick volume, which differs by broker.
• 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 Klinger oscillator? It uses the classic 34/55/13 lengths and the trend of high + low + close. The volume force is the simplified form used by many platforms: tick volume signed by that trend, without the cumulative range term of the original paper. Lines from other platforms can differ in size but cross zero at similar places.
Zero or trigger mode? Zero mode waits for the flow itself to change sides and trades less. Trigger mode reacts to the oscillator 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.
What should I change first? InpKVORangeMinATR, then InpKVOFast and InpKVOSlow. One change at a time, and look at drawdown 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. The Klinger oscillator is built from past bars and past tick volume 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.
