MT5 Expert Advisor: MACD histogram rule with trading-hours filter

I need an MT5 Expert Advisor (MQL5, full source code) that trades one simple rule based on the MACD histogram. All settings must be inputs.

Signal

- Timeframe input (default H1). Use closed bars only and act on the first tick of the new bar.

- MACD inputs: fast EMA, slow EMA, signal period (defaults 12, 26, 9).

- Signal line type input: SMA (like the built-in MT5 MACD) or EMA.

- Histogram = MACD line minus signal line.

- Histogram above 0: hold one long position. Below 0: hold one short position. Exactly 0: keep the current state.

- Allowed sides input: long and short / long only / short only. If a side is not allowed, stay flat instead.

Orders

- One position at a time per symbol and magic number. When the signal flips, close the current position and open the opposite one if that side is allowed.

- Fixed lot input. Optional stop loss and take profit in points (0 = off, default off).

- Must work on any symbol including metals, with broker symbol suffixes, on netting and hedging accounts, with the broker filling mode.

Trading hours

- Inputs: no-trade start hour and end hour in server time (same value for both = filter off).

- Inside the no-trade window the EA closes its position and does not open a new one. After the window it follows the signal again.

Restart safety

- After a restart, the EA finds its open position on the account by magic number and continues without opening a duplicate.

Delivery

- Commented .mq5 source that compiles with 0 errors and 0 warnings.

- No DLLs, no WebRequest, no license or account locks.

- A Strategy Tester report on XAUUSD H1, 2022-2025, 1 minute OHLC or better, showing trades.

- A short note listing the inputs.

Acceptance: I will run it in the Strategy Tester and check that entries and exits follow the histogram sign on closed bars, that no position is held inside the no-trade window, and that the allowed sides setting is respected.
