Specializing and evolving for domestic Japanese accounts! Prosperitas_Nexus_30 Version 3.4 Released
Specialized for domestic Japanese accountsEvolution
Prosperitas Nexus 30 Version 3.4 Released
━━━━━━━━━━━━━━━━━━━━
MT4 EA “Prosperitas Nexus 30” equipped with 30 strategy modules, designed for EURUSD
and released as version 3.4 rebuilt for Japanese domestic FX accounts (leverage 25x).
With the aim of balancing profit growth and drawdown suppression within the confined funds of domestic accounts, we have reworked capital allocation and settlement mechanisms.
This article introduces what changed and how, alongside a backtest comparison under the same conditions.
Thirty strategic intelligences into one decision
━━━━━━━━━━━━━━━━━━━━
■ Why we rebuilt it for domestic accounts
Domestic FX accounts are limited to a maximum leverage of 25x.
With the same capital, the amount that can be built is limited compared to overseas high-leverage accounts.
If you manage funds assuming overseas accounts while operating on a domestic account, you may encounter orders failing due to insufficient margin and positions biased leading to larger drawdowns.
Therefore, in version 3.4, we rebuilt from the ground up the lot calculation, position sizing, and settlement mechanics assuming a 25x leverage environment.
■ Three strategic enhancements in Version 3.4
The formulas used by each module and internal parameters are not disclosed to protect product logic.
Here, we explain the direction of the enhancements.
▼ ① Position design aligned to domestic margins
We redesigned the main modules’ positions to be sustainable within the domestic account margin.
If signals of the same direction continue, layering is only performed when there is ample margin after placing orders. Even as assets grow, the ratio of positions to funds does not balloon.
▼ ② Strengthening time-settlement modules and “variable-profit capture”
Among the 30 modules, some do not set a fixed take-profit price and hold for a certain time to capture price movement.
These modules target large profit per trade, but in the past profits could be pulled back by reversals.
Version 3.4 revises capital allocation to these modules and adds a “variable-profit capture” that raises stop-loss as unrealized gains reach a certain level, securing part of the profit.
As unrealized profits rise further, stop-loss moves up in tandem, and trades with strong upside are held to the end.
As a result, the win rate of time-settlement modules rose from 53.4% to 59.9%.
▼ ③ Responding to asset growth
When compounding increases assets, one-order size grows larger. In version 3.4, large orders are automatically split and placed, so you can continue trading with the calculated lot sizes even as assets rise.
■ Comparison with pre-improvement (same testing conditions)
Backtested with exactly the same conditions as the pre-improvement and Version 3.4.
Net profit increased about 2.9x, and the maximum drawdown relative to assets dropped from 39.90% to 32.45%. The main achievement is increasing profits while reducing the largest drawdown.
On the other hand, as asset size grew, the maximum drawdown at peak increased from 19.30% to 23.54%.
Testing conditions: EURUSD 15-minute chart / May 1, 2003 – May 29, 2026 / All ticks (modeling quality 90%) / Fixed spread 0.5 pips / Initial margin 10,000 USD / Leverage 25x / Compound interest
━━━━━━━━━━━━━━━━━━━━
This EA is EURUSD M15 only. It has not been tested on other currency pairs or timeframes, please do not use it for others.
Not compatible with MT5.
Some modules reference USDJPY price movements to determine USD strength/weakness
(No trading orders will be placed on USDJPY)
■ 23 years of backtesting results
Testing covered EURUSD from May 1, 2003 to May 29, 2026, assuming domestic accounts with 25x leverage.
▼ Verification conditions
・EURUSD 15-minute chart
・All-ticks model
・Modeling quality 90%
・Spread fixed at 0.5 pips
・Initial margin 10,000 USD
・Leverage 25x
・Compound interest operation
The verification period spans about 23 years, but since it includes parts of 2003 and 2026, calendar-year totals are 24 segments.
The year ending negative was 2014 (−0.8%).
This result is a simulation using historical data.
It does not guarantee future profits or the same performance.
In actual operation, results may vary due to variable spreads, slippage, order rejections, communication conditions, swap points, and other factors.
■ Spreads can significantly affect results
Prosperitas Nexus 30 includes trades where potential profit per trade is not large.
Therefore, the actual cost to operations (spread + transaction fees) directly impacts results.
The average profit per trade in the verification results under 0.5-pip spread was about 1.46 pips.
From this, the break-even point is about 2.0 pips of actual cost.
When spreads widen, modules that do not meet profitability conditions automatically stop, reducing the number of trades.
We recommend an average actual cost of 0.7 pips or less.
Please verify not the minimum spreads shown by the broker, but the actual average when the EA runs, including trading fees.
■ Risks to understand in exchange for high win rate
Backtest win rate was 77.07%, but the average winning trade was 1,655.41 USD and the average losing trade was −4,445.12 USD.
Some trades take wider profit targets than stop losses, so a single loss can offset several gains.
The maximum drawdown occurred during the European debt crisis in 2010, when assets fell 31.49% from the peak (32.45% including unrealized losses) from March 3 to May 25, 2010.
It returned to peak on September 22, 2010.
Also, in the downturn from July 2017, it took about 1 year and 8 months to return to the original asset level.
On a monthly basis, about 30% were negative, and there were periods of three consecutive negative months.
This EA is not a product that guarantees funds will grow quickly.
You need to operate with surplus funds that can withstand a decline of more than 30% and wait for a long time to recover.
━━━━━━━━━━━━━━━━━━━━
■ Refresh of the chart panels
Version 3.4 redesigned the left-top chart panel to display six lines of Japanese text.
A three-dimensional button-like design, with lines that change value will glow light-green for about 4 seconds to notify you.
Panel width automatically adjusts to the displayed content.
▼ Display settlement time on the chart
While holding time-settlement positions, a golden dashed line marks the planned settlement time, and remaining time is shown as “Time settlement remaining 2:15.”
When profit protection begins, a stop-loss line also appears on that position.
Now you can understand just by looking at the chart “Why is this position not settled yet” and “When will it settle.”
■ Auto-management features that support operation
Trading logic alone does not reduce the burden of long-term operation.
Prosperitas Nexus 30 includes features that automatically manage account environment and operational state.
■ Four setup items
■ Setup for EURUSD M15 chart
1. Prepare a domestic MT4-compatible account
2. Place the EA file into the MQL4/Experts folder
3. Restart MT4
4. Display USDJPY in the quotes, and open the USDJPY 15-minute chart once
5. Open the EURUSD 15-minute chart
6. Apply the EA to the chart
7. Enable automated trading
8. Check the panel (6 lines) and expert log
Some accounts attach “-cd” or similar to the USDJPY ticker name.
In that case, some modules that rely on dollar strength/weakness will stop (other modules will continue to operate)
If you want it to run 24 hours, VPS is recommended.
Please confirm brokerage’s EA terms, minimum lot size, and actual spread on official information before opening an account.
Account conditions are subject to change.
■ Who this EA is suitable for
・People who want to run automated trading on domestic FX accounts

・People seeking an EA that does not use grid or Martingale strategies
・People who can operate with long-term stagnation or drawdown understood
・People who can prepare low-spread MT4 accounts and VPS
・People who want to evaluate performance over a long period rather than short-term results
■ Who this EA is not suitable for

■ Things to confirm before purchase
Version 3.4 redesigned capital allocation and settlement to fit domestic account conditions, increasing profits while reducing maximum drawdown compared to before.
On the other hand, backtests recorded relative drawdown of 32.45%.
If spreads widen, performance may decline, and there is no guarantee of earning the same profits as in the past.
When evaluating the product, please check in order:
1. Your account’s actual cost (spread + fees) is 0.7 pips or less on average
2. Whether you can tolerate drawdowns of 30% or more with surplus funds
3. Whether you can provide a stable MT4 operation environment
4. Whether you can observe results over months to years
5. Whether you understand the product description, backtest conditions, and disclaimers
If these conditions are met, please review the latest specifications, price, terms of use, and support range on the product page before considering

■ Important matters
The results described in this article are from backtests using historical data under specific conditions.
They do not guarantee future profits.
In foreign exchange margin trading, slippage, spread widening, order rejection, and other factors may cause losses exceeding deposited margin.
Operate within surplus funds, and make final investment decisions at your own responsibility.
