Dear Traders,
All Expert Advisors from the PrizmaL series have received a new update: Prop Firm Risk Protection.
This update introduces advanced protection designed specifically for prop firm environments, including support for daily loss limits and overall loss limits, with both strict (initial balance) and relative (daily balance) calculation modes.
The system automatically monitors equity in real time and, if a configured limit is reached, closes positions and pauses trading to help maintain compliance with prop firm risk rules.
Full details and instructions are available here:

PrizmaL Gold – Update Release Notes
A new update for PrizmaL Gold has been released.
This version introduces significant structural improvements focused on execution quality, trade selection precision, and statistical robustness.
Key improvements in this update:
Implementation of Sortino Ratio–based optimization
The core model has been re-optimized using the Sortino Ratio as a primary evaluation and selection criterion.
Unlike traditional metrics such as Profit Factor or Sharpe Ratio, which treat all volatility equally, the Sortino Ratio specifically measures the relationship between returns and downside risk only.
This means the optimization process penalizes harmful volatility (losses and adverse movements), while ignoring beneficial volatility (profitable movements).
In practical terms, the Sortino Ratio works as follows:
• It calculates the average return generated by the strategy
• It measures only negative deviations from the expected return
• It evaluates how efficiently the system generates returns relative to downside risk
• Parameter sets with excessive drawdowns or unstable equity behavior are automatically filtered out
• Preference is given to configurations with smoother equity curves and controlled loss distribution
This allows the system to prioritize quality and stability of returns, rather than simply maximizing raw profit.
---
Increased Take-Profit targets
The Take-Profit levels have been significantly increased.
This adjustment allows the system to capture larger price movements when market conditions support extended directional continuation, improving the efficiency of high-quality entries.
---
Sell trades have been added
This version introduces full support for SELL positions.
Previously, the system operated under a more restrictive directional framework.
With this update, the model is now capable of identifying and executing high-probability opportunities in both upward and downward market movements, expanding the operational scope and improving overall market coverage.
---
Additional improvements
• Refined internal entry and filtering logic
• Improved trade selection discipline
• Enhanced structural stability of the model
• Extensive optimization and validation across multiple market conditions
This update represents a major improvement in the internal statistical framework and execution model of PrizmaL Gold.
You can download the updated version directly through your MetaTrader terminal.
Instructions:
Open your MetaTrader platform.
Go to Navigator.
Open the Market section.
Select My Purchases.
Find PrizmaL Gold in the list.
Click Install or Update to download the latest version.
If the update button does not appear immediately, please restart your MetaTrader terminal and check again in Market → My Purchases.
