EA Operations on FX Backtest Diary

Audit findings get measured before they get fixed

Tue, 21 Jul 2026 00:00:00 +0000

At one point I put the roughly 2,500 lines of my live EA’s source through a full bug audit. It produced 20 findings, ranging from genuinely dangerous holes (a halt latch that evaporated on restart) to a subtler species: places where the EA’s behavior quietly differs from the verified research code.

Running My EA on a Real Prop-Firm Account (Live Forward Log)

Thu, 09 Jul 2026 00:00:00 +0000

Most articles on this site are backtests. This page is different: it is the live forward record — what is happening right now to the EA running on a real account.

Ground rules for this log:

Only measured numbers from the actual account. If I ever quote an estimate or a simulation, I will label it as such.
Bad results get reported exactly like good ones. If the account fails the evaluation, this page will say so.
Updates are irregular (when something happens, plus milestones).

What is running, under what conditions

Item	Details
Account	Fintokei ProTrader Challenge STEP 1 (a real evaluation account)
Account size	¥10,000,000
Start date	2026-07-04
Pass conditions	+8% (then +6% in STEP 2). One breach of daily -5%, max -10%, or total open risk -3% means failure
EA	CoreSystemV14 — the MT5 implementation of the finalized system validated on this site (all 7 sleeves)
Risk settings	Challenge preset (base leverage 2.5 / cap 2.5 — stage 1 of the three-stage plan)
Safety guards	Flatten everything at daily -4%; halt new entries + flatten at account DD -7% (designed to step off well before the disqualification lines)

For transparency, the backtest-derived expectations (past data, 2015–2026, 11 years): +0.82%/month, PF 1.66, max DD -7.7% for the base system. Monte Carlo on the challenge settings says there is roughly a 30% chance of touching a -5% account drawdown at some point before passing, and about a 1% failure probability on the unstressed distribution. In other words: seeing a few percent of drawdown along the way is part of the plan.

I stopped hand-carrying EA updates to my VPS — a git-based auto-deploy for MT5

Wed, 08 Jul 2026 00:00:00 +0000

The expert advisors on this site run 24/5 on MT5 inside a Windows VPS, while all development happens on my local machine. Every EA change used to require this ritual:

Compile and test locally, push to git
Log into the VPS over Remote Desktop (RDP)
git pull on the VPS
Recompile in MetaEditor
Manually restart the EA on its chart

A few minutes each time, but with real money attached, every step demands attention. And in my setup, most EA code changes are made by an AI agent (Claude Code) — which meant the human’s only remaining job was being a courier who carries the AI’s work to the VPS. Time to automate the courier away.
