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.

A chart level is not a trading plan unless it can be converted into an executable order. This article explains how to turn a live buy or sell level into position size, spread cost, depth, limit price, and a no-trade threshold before the market forces the decision.
