【Discover Overview】
“Discover” is a GBP/USD scalping EA.
The timeframe used is 5 minutes; since it is GBP/USD, trades are most active from nighttime to morning in Japan due to the London and New York markets.
It is set not to trade during the weekend from Friday night to Monday morning.

Lot settings for long/short positions and trailing stops can also be changed from the parameters.

【Backtest Analysis】
Backtests: simple interest from 2009 for about 10 years, and compound interest from 2014 for about 5 years.
・Simple Interest
2009.01.01‑2019.06.30
Spread 1.5
0.1 lot fixed
Net profit +275,000 yen (average annual 26,000 yen)
Maximum drawdown −40,000 yen
Total trades 2,090 (annual average 199 trades)
Win rate 93.88%
PF 1.28
Drawdown was low, with favorable win rate and PF.
The high number of trades shows profits are reliably generated even with a slightly wider spread.

Recommended margin for 0.1 lot fixed
5.5 + (4.0×2) = 13.5 (万円)
Therefore, keeping around 140,000 yen would allow for safe operation.
The expected annual return in this case is 19.4%.
・Annual Revenue
Among the past 10 years' markets, only 2012 had a small loss.
In 2019, even though the period was half a year, profits were on par with or above the average gain over the past 10 years.

・Trading Window
It is clear that most trades occur in the late-night hours in Japanese time.
・Compound Interest

Spread 1.5
Net profit +7,608,000 yen
Maximum drawdown −1,749,000 yen
Total trades 1,063
Win rate 94.73%
PF 1.48
In five and a half years, increased from about 1,000,000 yen to 7,600,000 yen, more than sevenfold!
The maximum drawdown increased, but net profit, win rate, and PF are better than during simple-interest operation.
This can be attributed to the recent strong annual performance observed earlier.
The profit curve is not perfectly smooth, but it has grown profits without a large, sudden decline.

Since this is a one-position EA, if you consider operating “Discover” on its own, using compounding to seek higher profits is recommended. Because trading hours are limited, large losses are unlikely. With a high win rate, it should be able to grow your funds even in the short term.
