Overview
"Murasame" is an EA designed to capture the large price swings of GBPJPY over the medium to long term.
GBPJPY tends to sustain trends on the long side, while moving sharply over short periods on the short side. Based on this, the EA combines medium-to-long-term trend following on longs with short-term scalping on shorts.
The core strategy is long-side trading, with the short side designed only to the extent that it doesn't interfere with this. Shorting GBPJPY tends to result in losses under many strategies, partly due to frequently unfavorable swap rates. If you find this disadvantageous, shorts can be disabled via a parameter.
Longs aim to capture the early stage of a trend reversal and follow with a trailing stop once in profit. Since longs tend to be unfavorable on Thursdays and Fridays, no new long entries are opened on those two days.
No grid, no martingale, no averaging down. Hedging (holding both long and short simultaneously) can occur but can be toggled via a parameter. TP/SL are always set, so losses are limited.
Average holding time is about 18 hours for buys and 7 hours for sells. Positions may be held over the weekend.
According to backtest analysis, the EA trades roughly 100–150 times per year. In rare cases, there may be no trades for an entire month.
To control over-optimization and ensure reproducibility, this EA was developed using a combination of MT5 real tick testing and MT4 TDS (Tick Data Suite). (This development process has been used since version 4.9.)
To prevent unnecessary losses, the EA includes a range of supporting features that reduce operational mistakes, such as automatic chart setup, duplicate magic number alerts, and prevention of entries when funds are insufficient.
It also retains the detailed trade output logging and on-chart trade history display used during development.
This makes the EA approachable for those new to automated trading, while still meeting the needs of experienced users. Please start by testing it on a demo account.

Parameter Overview
- Initial Balance | Enter the starting balance so that compound lot calculation continues correctly even after a PC restart.
- Lot Growth Rate | Since rapid lot changes carry higher risk, this allows you to control the rate of lot growth.
- Allowed range from average spread | This is the allowable width from the internally measured average spread. During rollover hours, a maximum value alone is difficult to control, so setting a deviation range from the average allows broader coverage.
- Export trade info to CSV | Outputs details such as execution spread, average spread, and slippage at the time of trade.
*Note: Logs are prone to duplicate output when TP/SL is triggered — please be aware of this. - Show P/L pips on chart | Displays the trade line and pips on the chart.
