1. Not over-fitted
It did not stop at a single good result; it has passed multiple robustness checks:
Shifting the entry time by one hour at a time gives PF > 1.2 across almost the whole 12:00-22:00 band (a continuous plateau, not one standout point)
Robust to changing the SL/TP ratio to 3/6, 4/8 or 2/6 (PF 1.42-1.59)
Does not break when the Asian-range window is changed to 0-7, 0-8, 0-9 or 1-9
Walk-forward (best parameters chosen on 2023-24, then tested on unseen 2025-26) gives PF 1.67 = passes out-of-sample
2. Does not bleed in unfavourable years
Even across 2013-2015, including 2013 when gold crashed 28%, every year was positive (PF 1.08). It is not a fragile strategy that only wins when there is a trend; it holds at break-even or better against the wind.
3. Reproduced on three independent data sources
XM feed (2023-26), Dukascopy (2013-15) and TitanFX live XAUJPY (2025-26) all reproduce PF in the 1.5 range.
Frequently Asked Questions
Can I use the EA right after purchase?
Yes. The EA file (.ex4/.ex5) becomes available for download from your account page immediately after payment completes.
Does it support MT4 or MT5?
Platform compatibility varies by product. Please check the "Supported Platform" field on each product page. Many EAs support both MT4 and MT5.
Can I try EAs on a demo account?
Most EAs do not support running on demo accounts. To help you decide before purchase, every EA's backtest results are shown in the "Backtest" tab and forward test performance in the "Performance" tab on each product page.
What is the recommended margin or lot size?
Recommended settings are listed for each EA in the "Product Details" section of its product page. Excessive lot sizing can cause catastrophic losses at maximum drawdown.
Can I change my licensed account?
After purchase, go to "Licensed Account Switch" on My Page and enter the MT4/MT5 account number you want to bind. The change applies immediately. You can change once per 24 hours.
Are refunds or returns available?
Due to the nature of digital products, we generally cannot refund or accept returns after the authentication code has been issued. However, if the EA itself has a critical defect that prevents operation and the fault lies with us, we will handle the case individually. Please contact us via the inquiry page.
Do backtest results match live performance?
Backtest results are theoretical values based on historical data, while forward tests reflect live environment performance. Systre publishes forward test data for every EA on its product page so you can verify live performance before purchase. Spread and execution delays typically cause some divergence between backtest and live results.
