LondonScalper GBPJPY is a scalping EA that uses RSI and candlesticks on GBPJPY (pound / yen) to trade automatically at specific times and under specific conditions.
Entry
It decides entry timing based on multiple RSIs (RSI values for each period) and candlestick patterns.
Exit
Based on the close and open of the 5-minute candle, it closes the position when certain conditions are met.
Favorable markets
It is intended for markets with a clear trend, where the RSI and candlestick patterns are stable.
Unfavorable markets and timing to avoid
It is weak in sharply fluctuating markets and in markets where the RSI and candlestick patterns are unstable. Please be careful at times of large market movement, such as sudden market changes or around the release of major economic indicators.
Operating tips
Because it is based on a trend-following strategy, we recommend running it over a long span rather than judging it by short-term results alone. This EA does not guarantee future profits.

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.
