Position Size Calculator for Stocks
A position size calculator estimates how many shares fit a chosen loss limit: divide the dollar amount you are prepared to risk by the difference between your entry price and stop-loss price. Enter your account size, risk per trade, entry price and stop-loss price to see the share count, position value, estimated money at risk and position as a percentage of your account.
Trading Cost Calculator: Spread, Market Impact and Commission
A trading cost calculator estimates what a stock order may cost beyond its quoted share price: the bid-ask spread, market impact and broker commission. Enter the order value, share price, average daily volume, daily volatility and commission to see estimated costs in US$ and basis points, plus the order’s size relative to daily volume.
Portfolio Concentration Calculator: HHI and Largest Weight
This portfolio concentration calculator shows how much of your portfolio sits in each stock and sector. Enter each position’s value and sector to see its weight, a 0–10,000 Herfindahl-Hirschman Index (HHI), the effective number of stocks, your largest position and sector, and a concentration reading.
Value at Risk (VaR) Calculator for a Stock Position
A Value at Risk (VaR) calculator estimates a loss threshold for a stock position over a chosen number of days at a chosen confidence level. Enter the position value, daily or annualized volatility, a 95% or 99% confidence level, and the horizon to calculate parametric VaR in dollars.

Questions about PreTrAIde
What is PreTrAIde?
PreTrAIde is an AI pre-trade analysis platform for stocks. You build a basket of buy or sell orders, and before you place them it measures their cost, liquidity, risk and concentration and returns a GO, NO-GO or MODIFY verdict with the reasoning.
What is pre-trade analysis?
Pre-trade analysis is the check professional trading desks run before an order: what it will cost to execute, whether the stock is liquid enough for the size, how much risk it adds and how concentrated the portfolio becomes. PreTrAIde brings that discipline to private investors.
Is PreTrAIde a broker or an investment adviser?
No. PreTrAIde is analysis software. It never receives, transmits or executes orders, and its verdicts are decision support, not recommendations to buy or sell. You trade with your own broker.
Which stocks can I analyze?
US stocks and stocks listed on major European exchanges such as Euronext Paris, Xetra and the London Stock Exchange, in baskets of up to 5, 10 or 20 lines depending on the plan.
Is there a free trial?
Yes. The Basic plan starts with a 7-day free trial that includes one complete pre-trade analysis. The calculators, the glossary and the trading-cost pages are free without an account.

After an Earnings Surge, Re-Size the Position You Hold
