`HITEntryEA.mq5` is the entry-only Expert Advisor. It runs the H4/H1 Python signal workflow, applies the M15 confirmation rules, and submits pending orders. It does not manage filled positions. Stop management, trailing, and time-based position exits are delegated to `HITPositionManagerEA.mq5`.
The two EAs coordinate through matching `_Symbol` and `input_entry_magic_number` / `input_managed_magic_number`. The operating assumption is a retail hedging account.

@@ -45,12 +45,14 @@ The two EAs coordinate through matching `_Symbol` and `input_entry_magic_number`
- Pending orders receive `input_entry_magic_number`.
- The entry EA cancels expired pending orders, pending orders that conflict with the refreshed H4 state, and stale split-entry pending orders.
- When the range-breakout guard is enabled, upward breakout warning/confirmation cancels existing T4 Sell Limit orders and blocks new T4 entries until cooldown expiry. Downward breakout warning/confirmation cancels existing T2 Buy Limit orders and blocks new T2 entries.
- H1 Python results, candidate timestamps, and stale split-pending cleanup are processed before the spread gate; excessive spread only blocks new order submission.
- Filled-position SL updates, trailing, and time-based exits are not performed by this EA.
## 5. Risk Management
- The order limit counts only pending orders and positions matching `_Symbol` and `input_entry_magic_number`.
- Python process markers, process IDs, done files, and timeouts are monitored to prevent duplicate launches and stale-result reuse.
- If a done file exists but the expected result file is missing, the EA clears the done/running state and marks the same workflow for retry on the next tick.
- If the API TP direction contradicts the Buy/Sell price rules, the EA does not repair it; the existing price-consistency checks skip the order.
- The range-breakout guard only touches pending orders matching `_Symbol` and `input_entry_magic_number`; upward breakouts cancel T4 Sell Limit only, and downward breakouts cancel T2 Buy Limit only.
- `OrderSend` return values and `MqlTradeResult.retcode` are checked and logged.

## 7. Changelog
- 2026-06-14: Added initialization failure on non-hedging accounts. Moved H1 result loading before spread gating, added retry recovery for done-without-result Python states, and removed the unused filled-position time-exit path from the entry EA side.
- 2026-06-13: Connected the range-breakout guard from `HIT-EA_refactor_ver6.mq5` to the entry EA, including T4 Sell Limit retreat on upward breakouts, T2 Buy Limit retreat on downward breakouts, and cooldown-based new-entry blocking.
- 2026-06-13: Added `input_tp_multiplier`, `input_min_tp_points`, and `input_max_tp_points` to expand API-derived TP distances for both standard orders and per-slot split entries.
- 2026-06-07: Split entry responsibilities from `HIT-EA_refactor_ver6.mq5`; moved SLTP panel and filled-position management responsibilities to `HITPositionManagerEA.mq5`.
