# Custom EAs & indicators

A useful development brief describes triggers, exits, sizing, alerts and exceptions. We help turn those rules into a practical scope for MQL4, MQL5 and related utilities.

SCOPE

## Agree the outcome before work starts.

Separate the core version from optional features. A small, testable first version makes it easier to identify a rule misunderstanding before adding more complexity.

A working implementation is a software deliverable. Profitability and future market performance are not acceptance criteria we can promise.

YOUR PROJECT

## A clear handoff on both sides.

### What to prepare

- Written entry, exit, sizing or display rules

- Worked examples and what should happen in edge cases

- Required inputs, target platform and delivery preference

### What to agree in the quote

- An agreed feature list and usable program

- Source code when included in the scope

- Usage notes and test scenarios

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.
