Signalator Lot Size Evaluator MT5 is a free local MetaTrader 5 utility for manual traders who want to calculate an estimated position size before placing a trade.
It helps you plan a trade using the selected symbol, BUY or SELL direction, planned entry price, Stop Loss, optional Take Profit and risk percentage. The calculator uses current account information together with broker-provided symbol specifications to estimate the suggested lot size and key risk values.
The workflow is simple: define the trade setup → choose the amount of account risk → review the suggested lot size and broker conditions → place the trade manually if the setup is suitable.
Signalator Lot Size Evaluator MT5 is part of the Signalator Trading and Analysis Ecosystem — a growing family of practical MetaTrader tools designed for trade preparation, symbol and broker analysis, account monitoring, position management and everyday trading workflows.
The Lot Size Evaluator is available as a focused standalone utility for traders who only need pre-trade position sizing and risk calculation. The same functionality is also integrated into the broader Signalator Trade Summary Panel MT5, together with the functionality of Signalator Symbol Inspector MT5 and additional account, position and trading information tools.

Trade planning and lot-size calculation
Instead of calculating position size manually, enter the parameters of the planned trade and let the panel estimate the appropriate lot size for the selected risk.
The calculator supports:
- BUY and SELL direction - evaluate either side of the market.
- Editable symbol - evaluate another Market Watch symbol without changing the current chart.
- Manual entry price - define the intended trade entry.
- Stop Loss input - calculate trade risk from the planned SL level.
- Optional Take Profit - estimate potential reward and risk-to-reward ratio.
- Risk percentage - calculate the monetary risk and suggested position size from account size.
- Broker-aware lot calculation - use the symbol's tick value, tick size, point size and volume restrictions.

Why broker symbol data matters
The same nominal trade size can represent very different monetary risk on different instruments. Forex pairs, Gold, indices, crypto CFDs, stocks and other symbols may use different contract sizes, tick sizes, tick values, volume steps and trading restrictions.
Signalator Lot Size Evaluator MT5 reads the relevant MetaTrader 5 symbol specifications and uses them when estimating the position size. This makes the calculator useful not only for Forex, but also for instruments where a simple fixed pip-value assumption may be incorrect.
For a deeper inspection of broker symbol specifications, contract values, spread behaviour, swap settings and trading limits, you can use the free Signalator Symbol Inspector MT5.
If you prefer these tools together in a broader trading dashboard, Signalator Trade Summary Panel MT5 combines Lot Size Evaluator and Symbol Inspector functionality with additional account and position monitoring tools.

Local calculator only
This utility is designed for pre-trade calculation and evaluation only.
It does not open trades, close trades or modify trades. It does not provide trading signals.
The product does not use DLL imports, does not use WebRequest and does not connect to external servers. All calculations are performed locally inside MetaTrader 5.
Important
The suggested lot size and other calculated values are estimates based on account data and broker-provided MetaTrader 5 symbol specifications, including current prices, tick value, tick size, volume limits and trading conditions.
Different brokers may use different contract specifications, symbol names, suffixes, lot steps and execution rules.
Before placing a real trade, always verify the symbol, direction, entry price, Stop Loss, Take Profit, risk percentage, suggested lot size, broker volume limits and trading permissions.
Signalator Lot Size Evaluator MT5 supports manual pre-trade risk evaluation, but it does not replace trader judgement or broker-side validation.
