Common guidelines are as follows.

• RF 1–2: average

🔽 【Important】 Explanation of Lot Size

◆ Lots (initial lot) = 1.4

Larger lot sizes carry higher risk and higher return,
while smaller sizes are lower risk and lower return.

The value 1.4 is, for a 1,000,000 yen account,
the setting that achieved the best profit efficiency without dipping into the principal.
(1 lot = 100,000 base currency; in this backtest 1.4 means 140,000 base currency)

Also,
the value of 1 lot depends on the FX broker you use, so please confirm.

Generally, 1 lot is 1,000, 10,000, or 100,000 base currency,
and even in the same broker, the composition of 1 lot may vary by the course used, so please check.

This backtest lot setting is an example assuming a 1,000,000 yen account.

Depending on the broker and the currency per lot,
risk can vary greatly, so
adjust to your own environment.

If funds are small or you want to limit risk,
always operate with a reduced lot size.

🐉 Recommended lot sizes for domestic FX brokers

◆ Lots = 0.6

Assumptions

• GBPJPY approximate rate: around 190 yen
  
  

• 1 lot = 100,000 currency units
  
  

• Leverage: 25x
  
  

• Collateral: 1,000,000 yen
  
  

■ Estimated required collateral for 1 lot of GBPJPY

100,000 × 190 ÷ 25 ≒ 760,000 yen

As mentioned above, this EA starts with 1,000,000 yen,

and backtest implies operating at a maximum lot that does not breach the principal,

assuming 1.4 lots (140,000 currency) for operation.

However, in domestic FX, maximum leverage is 25x, so

entering at 1.4 lots is not possible due to insufficient collateral,

and entry itself cannot be performed.

Refer to the table above for required collateral by lot,

and set the recommended lot for domestic FX brokers to 0.6 lots per 1,000,000 yen of capital,

and set the initial lot of this EA to 0.6 lots (60,000 currency).

Lot sizes can be freely changed via parameter settings, so

adjust to your preferred lot size yourself.

🔽 Lot-based Reference Backtest Results

This EA allows you to control risk and return by adjusting the lot size.

Below are reference backtest results by lot size.

■ Starting funds 1,000,000 / Lot 1.4 (maximum assumed)

• Net profit: about 8,947,428 yen

• Max drawdown: about 950,841 yen

• Funds over about 11 years: about 10x

■ Starting funds 1,000,000 / Lot 0.6 (initial lot: recommended by domestic FX)

• Net profit: about 3,834,612 yen

• Max drawdown: about 407,503 yen

• Funds over about 11 years: about 4.8x

■ Starting funds 500,000 / Lot 0.3

• Net profit: about 1,917,306 yen

• Max drawdown: about 203,752 yen

• Funds over about 11 years: about 3x

📊 About Lot Size and Risk

Lowering the lot size reduces net profit, but also proportionally reduces max drawdown, enabling risk-controlled operation.

Adjust lot settings to suit your funds and risk tolerance; no risk in tuning to your environment.

📝 Developer's Comment

WhiteDragon was developed with the aim of “protecting assets long-term while steadily increasing them.”

GBPJPY exhibits large moves, but the logic is designed to leverage that characteristic while avoiding aggressive entries.

Trade frequency is kept modest, providing a sense of reliability as an automated trading system.

For those tired of discretionary trading or who want to build wealth over the long term, this EA is highly recommended.
