MQL4/MQL5 • PINE SCRIPT • CTRADER • EDITABLE SOURCE

Fix, Specify or Build Trading Software You Can Actually Test.

I turn explicit rules and authorized source code into MQL4/MQL5, Pine Script and cTrader software. You get readable source, clear acceptance cases and a reproducible test plan. No performance promises.

MT5 EA Acceptance Harness

A non-trading MetaTrader 5 script that executes eight synthetic entry-state fixtures before timing, duplicate, cooldown and daily-lock rules are connected to broker behavior.

MT5 Cash Risk Probe

A read-only MetaTrader 5 script that estimates entry-to-stop cash loss in account currency, reserves explicit costs and floors volume to the broker grid without sending an order.

Pine Script v6Public Pine v6 source

Pine v6 Partial Exit State Inspector

A deterministic Pine Script diagnostic that makes initial-versus-remaining quantity semantics explicit for 50%, 33% and 25% partial exits and emits each tier once on a confirmed bar.

From requirements to tested source code

The goal is not merely code that compiles, but behaviour that can be checked against the agreed specification.

01

Audit

I freeze entry, exit, risk, sessions, ownership and edge cases in writing.

02

Build

I implement the agreed solution with explicit state, guards and useful logging.

03

Verify

I verify compile checks, acceptance examples, parameter sanity and failure modes.

04

Deploy

You receive the agreed source, configuration, test notes and setup guide.

Describe the problem

Send the rules, editable source or screenshots you are allowed to share. I will reply with what is feasible, what is missing and the smallest fitting next step.
