[Real Data Release] Running a self-made EA on a demo for 10 days. The behind-the-scenes of a net profit of +131,000 yen and the environment settings that support steady operation | ORB_RR_Portfolio

The self-made EA ORB_RR_Portfolio, which is under development and validation, started forward testing on a new demo environment from 10/19.

Today we disclose all actual MT5 operating data from roughly the first 10 days since launch (10/19–10/28) and the real numbers of the runtime environment supporting this system.

1. Environment selection to run 24/7 and eliminate wasteful costs

To ensure this EA performs as in the backtests and minimizes unnecessary losses (drawdown), it has been running continuously for 24 hours in the following environment.

Trading account: XMTrading KIWAMI extreme account (Demo)

Reason for selection: swap-free with extremely tight spreads. Reducing unnecessary negative swap for positions spanning days and minimizing entry costs (spread) is considered the first step toward “stable operation without going bust.”

Operating server: Sakura VPS

Reason for selection: to ensure a stable 24/7 communication environment and low latency, and to prevent order slippage.

Stable operation is very important. Previously we used another provider, but there were numerous issues such as reboots and EA not running… so we switched.

MT5 also sends frequent notifications to confirm if MT5 is running.

2. Forward test results for 10 days (2026.10.19 – 10.28)

The confirmed performance over the first 10 days since launch is as follows.

Initial working capital: ¥1,000,000

Net realized profit: +¥131,659

Current account balance: ¥1,131,659

Open positions: 0 (completely no positions, all closed)

【Profit by Instrument (Data Breakdown)】


Breakdown of realized profit by instrument

GOLD: +¥60,486 (6 closes)

GER40Cash (Germany stock index): +¥33,255 (5 closes)

GBPJPY (Pound/Yen): +¥16,620 (1 close)

GBPUSD (Pound/Dollar): +¥14,088 (profit taken on 10/28)

USDJPY (Dollar/Yen): +¥7,210 (1 close)

Without relying on a single currency pair, the strengths of a “multi-asset portfolio” where precious metals (GOLD), equity indices (GER40), and currencies (USDJPY, GBPJPY, GBPUSD) complement each other’s drawdowns are clearly demonstrated.

3. Objective analysis as a developer and future prospects

Achieving +¥131,659 (+13.1%) over 10 days is a pleasant start, and I’m glad it’s off to a smooth beginning.

However, as a developer, my view is that “this is only 10 days of data, and proving that this system is truly reliable requires far more data.”

The market environment and a coincidental trend may have contributed to these results, so we will continue the forward testing calmly without getting carried away.

Dynamic lot scaling (compound interest capability) with capital growth
This EA includes a built-in logic to automatically optimize the entry size (lot size) as the account balance grows.

In these 10 days, the account balance grew from ¥1,000,000 to over ¥1,130,000, so in future trades the entry lot size will automatically increase in steps while maintaining a safety margin.

We will continue to verify and report how the compounding mechanism works, keeping risk management principles (allowed loss rate) while the asset size increases, and the profit growth rate accelerates.

Summary
10-day result: net profit +¥131,659 (no positions, all closed)

KIWAMI extreme account’s swap-free and tight spread, plus VPS environment contribute to low-cost operation

Since data volume is still small, we will continue to disclose forward performance honestly on a weekly to biweekly basis

Please look forward to the next data update as well.
