# MT4 to MT5 conversion

Move indicators, EAs and utilities across platforms with an explicit behavior checklist. The work starts from available source and dependencies, then covers implementation and comparison.

SCOPE

## Agree the outcome before work starts.

Changing a filename is not a conversion. Trading access, indicator data, event handling and program dependencies need review in the target platform.

Only have EX4? Start with a recovery assessment rather than treating a compiled file as editable MQ4 source.

YOUR PROJECT

## A clear handoff on both sides.

### What to prepare

- MQ4 / MQH source and all dependencies

- Reference parameters, charts and expected behavior

- Target MT5 setup and account model where relevant

### What to agree in the quote

- Agreed MQ5 source and matching EX5 build

- Notes on platform differences and changed interfaces

- Comparison results within the agreed test conditions

PROCESS

## Assess. Agree. Verify. Deliver.

- 01 Describe & send Identify the platform and goal; share files privately.

- 02 Agree the scope Confirm feasibility, output, price and delivery window.

- 03 Review the build Compare against the original under agreed conditions.

- 04 Approve & receive Settle the agreed balance and receive the final files.
