Grid Williams Percent Range EA
SHORT DESCRIPTION
The Williams Percent Range entry from the original product, now driving a complete grid, hedge and cycle engine. A cross back out of an extreme zone arms the first level. Everything after that - the ladder, the fragmenting closer, the target slicer, the reopen guard, the optional hedge cycle - is handled by an engine that was built to keep a grid alive rather than to hope it never goes wrong.
WHAT CHANGED FROM THE ORIGINAL
This product already had a grid. What it did not have was this engine.
The original closed the oldest order against the newest and waited for that pair to cover its own cost. When the market did not come back, nothing closed and the book grew. That is how almost every grid works, and it is the reason almost every grid eventually stops working.
The entry logic is unchanged - it is reproduced exactly, the same indicator, the same levels, the same conditions. Everything behind it has been replaced with the full machine: a fragmenting closer that scans combinations of both ends of the book, a target slicer that part-closes an order it cannot afford to close whole, a ledger that remembers what is still owed across restarts, a reopen guard, a verification state machine, and an optional hedge cycle.
If you own the original, this is the same idea with the part that actually decides whether a grid survives.
WHAT THIS EA IS
Three engines that share one chart and one account, wired together so money only ever flows in one direction.
1. THE OPENER - WILLIAMS PERCENT RANGE
Where the close sits inside the period's range, measured DOWN
from the high. The scale runs from zero at the top to minus one
hundred at the bottom, which catches people out the first time.
Minus twenty is therefore near the HIGHS - overbought - and minus
eighty is near the lows. The inversion is historical rather than
meaningful, but the defaults here are the conventional ones and
it is worth reading them slowly before changing anything.
The reading itself is one of the most responsive in common use,
because there is no smoothing anywhere in it. It is a direct
measurement of the current bar against the window's extremes, and
it reaches its limits quickly and leaves them quickly.
As everywhere else in this range, the trigger is the EXIT from an
extreme rather than the entry into one. A reading pinned at minus
ninety tells you the market is working; the moment it comes
unpinned tells you it has stopped.
You can also keep a plain distance trigger, or require both: the indicator must agree with a real move before a single order is sent.
2. THE LADDER
Once a cycle is armed, the grid builds. BUY and SELL grids run independently, each with its own anchor, its own level counter, its own spacing and its own bar gate, so a market that trends one way and ranges the other is not forced into a single model. Single-grid mode is there when you want one direction at a time.
Spacing is fixed points or ATR-driven, with a floor, a ceiling and an option to freeze the ATR value for the whole cycle so the spacing does not drift under you mid-cycle. A per-level multiplier lets the grid widen as it goes deeper.
Lots climb by multiplication or by addition. Additive is the honest choice for most accounts: 0.01, 0.02, 0.03, 0.04 rather than a curve that doubles into margin call. Auto-lot scales the starting size with the balance, and scaling down is opt-in rather than assumed.
3. THE CLOSER - AND THIS IS THE REAL DIFFERENCE
A normal grid closes the oldest order against the newest and waits for the pair to cover its own cost. When the market does not come back, nothing closes, and the book grows.
This closer does not wait.
It scans combinations of both ends of the book - several of the oldest orders against several of the newest - and ranks the qualifying combinations by how much of the book each one clears. It counts swap and it counts commission, both sides, from your own trade history rather than from a number you typed in.
When no whole combination can cover the target, it buys a SLICE. Part of the oldest order is closed, paid for by the profit the newest orders have already made, and the rest of that order is remembered in a ledger. The ledger survives restarts, reattaches and terminal crashes, and the part already killed is rebuilt from deal history every time rather than trusted from storage. Over several slices the oldest, heaviest order is retired piece by piece while the market does whatever it wants.
A reopen guard refuses any closure that would immediately reopen the level it just closed, which is the quiet way most grids churn their own account into commission.
4. THE HEDGE CYCLE - OFF BY DEFAULT
An optional volume engine. It opens a perfect hedge - equal BUY and SELL on a rotating list of symbols - and then retires it in slices, each slice funded by a small surcharge added to the closures the grid was making anyway. The hedge is held in balance, verified on a timer, and repaired automatically if one leg is left naked.
There are hard limits on what the hedge may cost. A cap in money on a single closure, a cap as a percentage of any closure's target, and a weekly cash-day window that can hold new cycles and new slices before a withdrawal.
This is off by default and deliberately so. With it off, this EA is the Williams Percent Range entry driving a dual grid with a fragmenting closer, and nothing else is touched.
5. EXECUTION YOU CAN AUDIT
Every closure is a plan that is scanned, sent leg by leg, and then verified against the deal history. A leg that does not fill goes to a retry queue instead of being assumed. A market that refuses orders makes the EA wait rather than burn its retry budget. A book that changed between the scan and the send aborts the plan.
There is a run mode that scans and reports without trading, so you can watch what it would have done before you let it do anything.
6. THE PANEL
This product has its own panel, not a shared one. The theme is PERCENT RANGE: this product has its own panel, not one shared with the rest of the range. The theme is PERCENT RANGE: olivine owns everything the grid does and mauve owns everything the hedge does, on its own palette, typeface pairing, corner layout and row pitch.
Both cards are drawn in English with an Arabic line underneath, and both can be switched off. In a non-visual backtest nothing is drawn at all, so optimisation runs at full speed.

REQUIREMENTS
A HEDGING account is required. On a netting account every grid level merges into one position, so there is nothing to fragment and no way to hold a hedge. The EA checks this at startup and stops with a clear message rather than misbehaving quietly.
Works on any symbol and any timeframe. No DLLs, no external indicator files, nothing to install beyond the EA itself. The strategy maths is written into the EA, so the reading on the chart and the reading it trades from are the same number.
A NOTE ON EXPECTATIONS
A grid is a way of managing a position, not a way of predicting a market. The Williams Percent Range entry decides when to start and which way to face. The closer and the slicer are what keep a cycle from becoming permanent. Size the ladder for the account you actually have, test on your own broker's spreads and swap, and start with the hedge cycle off.
Set files for the main configurations are included. Questions and setup help are welcome through private message.
