39｜ EA is not a program but an operations system

?Introduction

Many people think EAs are programs.

But in reality, that isn’t the case.

EAs are operation systems.

?Code is only part of it

What makes up an EA includes,

not only code.

Backtesting.

Forward testing.

Lot sizing.

Stop criteria.

Restart criteria.

Operational rules.

All of these constitute an EA.

?Even after sales, it continues

An EA isn’t finished once it’s sold.

It continues after sale.

Market analysis.

Improvements.

Optimization.

Updates.

Maintenance.

These are required.

?Think of it as a financial system

EAs handle money.

In other words,

it is Software,

and also a financial infrastructure.

Therefore,

quality management becomes important.

?Role of the developer

Write code.

That alone isn’t enough.

Monitor.

Evaluate.

Improve.

That is required.

? MAEP perspective

MAEP isn’t a collection of codes.

MetaTrader Engineering.

It covers from development to operation.

✅ Summary

EAs are not programs.

They are financial systems, including operations.

By simply adopting that perspective,

EA development changes dramatically.
