Grid Stochastic Oscillator EA

Try it before you pay a cent: load Grid Stochastic Oscillator EA into the MetaTrader 5 Strategy Tester, turn on visual mode and watch the panel track %K and %D, wait for a stretched market to turn, open each level and bank each closure candle by candle.

A GRID THAT WAITS FOR AN EXHAUSTED MARKET TO TURN BEFORE IT OPENS A SINGLE ORDER.

Grid Stochastic Oscillator EA lets the classic Stochastic Oscillator decide when a move has been stretched into the oversold or overbought zone and is starting to turn back, then hands the position to a complete grid management engine that keeps paying down the oldest exposure a piece at a time.

At a glance

• Entry comes from %K crossing %D on a closed bar after %K has visited the oversold or overbought zone, so nothing repaints.

• The new Zone-Memory Guard keeps a valid turn alive when %K hooks out of the zone one or two bars before the cross, instead of throwing a good setup away for being one bar late.

• Profits are taken in groups of the oldest and newest orders, with partial slices when a whole old order is still too heavy.

• No stop loss and no forced close-all; protection blocks new levels instead of throwing the book away.

• Hedging and netting accounts are both handled, and every limit is a visible input.

QUICK START

Good first symbols: EURUSD or XAUUSD. Good first timeframe: H1. Lot: the default 0.01 with the additive ladder. Mode: begin in Scan only, read the plans on the panel for a while, then switch to Armed. Always test on your own broker's data first, because spreads, swaps and commissions are never the same twice. On a small account, keep the default lot and let the Strategy Tester show you how deep the book can go on your symbol before you go live.

Why the Stochastic, and why it matters for a grid

The Stochastic Oscillator answers one plain question: where did the last close finish inside the recent high-low range? A reading near the top means price keeps closing near its highs; a reading near the bottom means it keeps closing near its lows. The fast line, %K, and its smoother partner, %D, travel between 0 and 100. When %K has been pressed into the oversold area and then crosses back above %D, sellers have run out of push for the moment; the mirror picture in the overbought area shows buyers tiring. Most grids start wherever price happens to be standing. This one waits until the oscillator shows a stretched market starting to turn, and only then gives the grid permission to build.

What is new in this release

The Zone-Memory Guard is the fresh idea in this EA. Real markets rarely deliver a textbook cross exactly on the bar that leaves the zone: often %K climbs out of oversold first and only crosses %D a bar or two later. A strict rule would ignore that turn completely. The guard looks back a few bars before the cross, and if %K touched the zone within that short memory, the turn still counts. Set it to 0 for the strict classic rule, or raise it a little for a more forgiving one. The panel gains a STOCH ZONE row that shows whether %K is OVERBOUGHT, MID or OVERSOLD, the trend filter state and whether the memory currently has a BUY or a SELL armed. Margin-level timeframe safety is also built in and is switched off by default.

How one cycle unfolds

1. The reading. At every closed bar the EA reads %K and %D from the built-in MetaTrader 5 Stochastic Oscillator. The forming candle is never used, so what you see on history is what the EA saw at the time.

2. The cross. A BUY cycle is considered when %K crosses above %D; a SELL cycle when it crosses below. An optional minimum gap can demand that the two lines have really separated on the signal bar.

3. The zone check. A BUY needs %K to have been at or below the oversold level, a SELL at or above the overbought level, on the bar before the cross or within the Zone-Memory window.

4. The optional trend filter. An EMA can confirm the side: trade only with it, trade only against it as a fade, or leave it out.

5. The rhythm. A quiet gap of bars between accepted signals stops a choppy session from firing a burst of cycles, and a signal can stay valid for a few bars when a level could not be placed straight away.

6. The ladder. Levels open at a fixed or ATR-based distance, with a floor, a ceiling and an option to freeze that distance for the whole cycle. BUY and SELL grids can run side by side or one direction at a time.

7. The harvest. The closer searches for groups made of the oldest and newest orders and closes a group as soon as its combined result, after swap and commission, clears your target. When the oldest order is still too heavy, only a slice of it is closed, funded by profit that is already open.

8. The guard rails. A reopen guard refuses a closure that would immediately reopen the same level. Every leg is checked against the deal history, failed legs wait in a retry queue, and a plan is dropped if the book changes between the scan and the send.

9. The optional hedge cycle. Off by default. When enabled it holds a balanced pair on a symbol you choose and retires it in equal slices paid for by a small surcharge on closures the grid is already making.

The panel

The panel lives on the left and keeps the right side and the price scale free. It shows symbol and magic number, a status pill (ARMED, SCAN ONLY or PAUSED), grid mode, lot step, spacing, banked profit, the book in lots with its net result, the closing plan for each side with its own close button, the order list, a STOCH PULSE row with live %K and %D, the slope, the leading side and the bars since the last cross, and the STOCH ZONE row with the zone, the trend filter and the memory state. Buttons switch Armed / Scan only, Pause / Resume, chart marks and slicing. The Hedge Vault card docks right under the main panel and follows it when you drag or minimise. It scales to the screen and draws nothing in a non-visual backtest, so optimisation stays quick.

Safety in your hands

No stop loss and no forced close-all: when a limit is reached, new levels are refused while existing orders keep being managed.

Before every order the money check asks one honest question: is there enough free margin, with a buffer, for this order?

Caps on levels per grid, orders per side and lot per order keep the ladder bounded, and the lot ladder stops growing at the level limit.

On netting accounts the margin of the merged position is held within a percentage of equity.

Optional margin-level timeframe safety: when the margin level falls to the levels you set, the working timeframe steps up so signals come less often, and it steps back only after margin recovers past a hysteresis cushion. Off by default.

Each instance isolates itself by symbol and magic numbers, so several copies on different charts never touch each other's orders or saved state.

Scan only mode shows every decision on the panel without sending a single order.

Who it suits, and who it does not

It suits traders who like a clear, rule-based reason for every new cycle, who prefer many small closures over one big target, and who are happy to size the lot for their own account. It does not suit anyone who wants a stop loss on every order, a fixed monthly figure, or a set-and-forget robot on a tiny balance with large lots.

Honest expectations

A grid manages a position; it cannot see what comes next. Grid Stochastic Oscillator EA is selective about when a cycle begins and works steadily to keep each cycle short and each old order shrinking, yet a long one-way trend can keep the oscillator pinned in a zone and the book open for a while. Choose a lot your account can carry through that, test on your own broker first, and let the Strategy Tester show you its rhythm before you go live. It runs on any symbol and timeframe and needs no DLLs and no extra files.

If you try it, an honest review describing how it behaved on your account, good or bad, helps other traders make a better decision.
