Lot Architect is a trade panel and risk-based position size calculator for MetaTrader 4. It helps calculate lot size from the selected risk, displays trade parameters before entry, and supports Market, Limit and Stop orders from the chart.
The utility is designed for traders who want a structured workflow for position sizing, stop-loss placement, take-profit planning and order execution.
Purpose
Before opening a trade, a trader needs to know the lot size, stop-loss distance, amount at risk, required margin and reward-to-risk ratio. Calculating these values manually can take time and may lead to mistakes, especially when trading different symbols such as Forex pairs, Gold, indices or CFDs.
Lot Architect brings these values into one panel on the chart. The trader sets the Entry, Stop-Loss and Take-Profit levels, selects the risk method, and reviews the calculated result before placing an order.
Main Features
- Risk-based position sizing by account percentage, account currency amount or fixed lot size
- Entry, Stop-Loss and Take-Profit levels that can be moved directly on the chart
- Live calculation of lot size, risk, reward, margin and reward-to-risk ratio
- Support for Market, Limit and Stop orders
- Multiple take-profit targets with volume allocation
- Commission input for more complete trade calculations
- Risk and reward zones displayed on the chart
- Portfolio risk overview for current positions
- Dark and light panel themes
- Keyboard shortcuts for common actions
Trade Panel Workflow
The Main tab is used for the basic trade setup. Select Long or Short, choose the order type, set Entry, Stop-Loss and Take-Profit, then choose how the position size should be calculated.
The Risk tab contains account and risk settings. The trader can choose whether calculations are based on balance, equity, free margin or a custom account value.
The Trade tab contains execution-related settings such as slippage, spread limit, order comment, magic number and pending order expiration.
The Info tab shows account and symbol information that may be useful when preparing a trade.

Notes
Lot Architect is a utility for position sizing, risk calculation and order execution. It does not predict market direction and does not guarantee trading results. All trading decisions and risk remain with the user. Test the product on a demo account before using it on a live account.
A MetaTrader 5 edition is available separately from the same author.
