# Changelog

## Staged polish — 2026-09-05

- Preserved the author's rolling signal-history arrays and false-to-true transition flow.
- Invalid indicator reads are skipped instead of being recorded as a false state that could re-arm a stale signal.
- Prevented `EMPTY_VALUE` from being inverted into a false-positive signal.
- Added input validation and an MT4 shift boundary check.
- Applied the configured MT5 deviation and symbol filling policy.
- Added MT5 trade-result checks with broker return details; retained the MT4 order-error checks.
- Kept the original input concepts and fixed-lot scope; dynamic risk sizing is intentionally not included in this mini framework.
