Thank you for visiting the Naminori product page.
Naminori is a fully automated trading system specialized in swing trading JPY cross pairs. All trades are executed automatically without manual intervention.
The forward testing signal for this EA is publicly available on the following page:

Features
1. Risk Diversification Through Multiple Strategies
Naminori consists of four independent strategies designed to adapt to different market conditions.
Each strategy operates independently based on its own trading logic, without sharing signals or decision-making logic with the other strategies.
By not relying on a single strategy, Naminori aims to reduce the impact when a particular market environment is unfavorable for one strategy and achieve better risk diversification.
2. Strict Position Management
Each strategy is limited to a maximum of one open position at a time. Naminori does not use grid trading or martingale strategies.
The entire system is also limited to a maximum of four open positions, helping to avoid excessive concentration of positions.
This approach is designed to reduce the risk of large drawdowns and aim for more stable long-term operation.
3. Let Profits Run, Keep Losses Small
The basic concept behind Naminori is simple.
When a strong trend develops and its direction matches the strategy's trading conditions, the system aims to capture larger profits.
On the other hand, when market conditions are unfavorable or a sufficient trend does not develop, the system aims to exit trades with as small a loss as possible.
Rather than attempting to profit in every market condition, Naminori is designed to prioritize capital protection during unfavorable conditions and profit expansion during favorable conditions.

Input Parameters
Global Settings
Display comments on chart (ON/OFF) – Show or hide information displayed on the chart.
Enable daily loss limit – Enable or disable daily drawdown protection.
Daily loss limit (%) – Maximum allowable daily loss based on the account balance.
Maximum total open positions – Maximum number of open positions across all strategies.
Use separate lot settings per logic – Enable separate lot size settings for each strategy.
Global Lot Size Settings
[Global] Lot calculation type – Select either fixed lot size or dynamic lot sizing.
[Global] Risk Mode – Select the risk type used in dynamic lot mode.
[Global] Fixed lot size – Lot size used when fixed lot mode is selected.
[Global] Dynamic lot scaling factor – Specify the scaling factor used in dynamic lot mode. This setting applies when Risk Mode is set to Manual.
In dynamic lot mode, the scaling factor and lot size have an inverse relationship.
A higher value results in a smaller lot size and therefore lower risk, while a lower value results in a larger lot size and higher risk.
Strategy Settings (Strategies 1–4)
Enable Strategy – Enable or disable each strategy.
Magic Number – Magic number assigned to each strategy.
Spread limit (points) – Maximum allowable spread for each strategy.
Strategy-Specific Lot Size Settings
These settings apply when "Use separate lot settings per logic" is set to true.
Lot calculation type – Select either fixed lot size or dynamic lot sizing.
Risk Mode – Select the risk type used in dynamic lot mode.
Fixed lot size (if fixed lot mode is used) – Lot size used when fixed lot mode is selected.
Lot scaling factor (for dynamic lot mode) – Specify the scaling factor used in dynamic lot mode. This setting applies when Risk Mode is set to Manual.
Daily Loss Limit
You can configure "Enable daily loss limit (ON/OFF)" and "Daily loss limit (%)" according to your preferences.
When "Enable daily loss limit" is set to ON, the system monitors the account balance based on the balance at the beginning of the current trading day.
If the loss reaches or exceeds the specified percentage, all open positions managed by this EA are closed, and trading is suspended until the next trading day.
The protection applies only to orders using the Magic Numbers assigned to the strategies in this EA.
The starting balance is reset daily at the New York rollover (17:00 New York time). This follows the standard trading-day reset convention commonly used in the forex market.
The account balance is checked every 15 seconds.
Additional Information About the Lot Scaling Factor
The following are the estimated maximum drawdown ranges for the main scaling factor settings:
3000 (Medium Risk) ⇒ 20–30%
5000 (Conservative) ⇒ 15–20%
7500 (Low Risk) ⇒ 10–15%
10000 (Very Low Risk) ⇒ 5–8%
1500 (High Risk) ⇒ 50–60%
These estimates are based on backtesting and forward testing results.
Actual drawdown may vary depending on market conditions and changes in volatility.
