Lot Size Calculator, Risk Manager and Trade Panel for MetaTrader 4
Lot Size Calculator Risk Manager Panel MT4 (This is the free edition of Lot Architect PRO) is a trading utility for MetaTrader 4 that combines a lot size calculator, position size calculator, risk manager and trade panel in one chart-based interface.
The utility calculates position size from a selected risk value and displays the planned trade information before order execution. Entry, Stop Loss and Take Profit levels can be entered manually or adjusted directly on the chart.
Main Features
Position Size Calculator
Calculate the position size using:
-
Risk percentage of the selected account value
-
Fixed risk amount in account currency
-
Fixed lot size
The calculation can use balance, equity, free margin or a custom account value as the calculation basis.

The panel displays the main risk and reward information for the planned trade:
-
Position size
-
Required margin
-
Risk amount
-
Risk percentage
-
Potential reward
-
Risk-to-reward ratio
This allows the planned position size and risk parameters to be reviewed before sending an order.
Entry, Stop Loss and Take Profit
Entry, Stop Loss and Take Profit levels can be entered by price or adjusted using chart lines.
When the price levels are changed, the position size, risk, reward and risk-to-reward values are recalculated.

Trade Panel
The trade panel supports manual order preparation and execution for:
-
Market orders

Important Information
This utility is designed for position sizing, risk management and trade execution support.
It does not predict market direction and does not generate guaranteed trading results.
The calculated position size depends on the account balance or equity, selected risk value, entry price, Stop Loss level, symbol contract specifications and broker conditions.
Always verify the calculated values and test the utility on a demo account before using it in live trading.
All trading decisions and risks remain the responsibility of the user.
"Lot Architect MT4 is very user-friendly and makes trading so much easier and more convenient. The lot size calculation is fast, and the built-in commission calculator is highly useful. The user interface also looks great with nice colors. However, there is a delay when switching menus. For instance, when clicking to change from 'Long' to 'Short', the system lags and takes several seconds to respond. Additionally, I would like to suggest adding a Break-Even (BE) menu function. Lastly, please note that the free version only has a trial period of about 2–3 days."
