The difference at a glance
| Danelfin | PreTrAIde | |
|---|---|---|
| Primary question | How does a stock rank on an AI measure associated with its probability of beating the market? | What does an analysis of this proposed basket indicate before an order is placed? |
| Starting point | A stock to evaluate or compare | One or more stocks, each with a buy or sell side, quantity and execution conditions |
| Main output | An AI stock score | A GO, NO-GO or MODIFY verdict for the basket and each line, with reasoning |
| What the output means | A comparative stock assessment, not a trade-specific execution estimate | Decision support on the submitted basket, not a recommendation or order |
| Trade size | Not the central input to a stock ranking | Included through the quantity supplied for each line |
| Basket-level analysis | Not the purpose of an individual stock score | Includes concentration and portfolio breakdowns |
| Order execution | An investor uses their own broker | PreTrAIde never receives, transmits or executes an order |
These are different analytical lenses, not interchangeable verdicts. A stock can rank well in a scoring system while a particular order in that stock presents liquidity, cost or concentration concerns. Equally, a manageable estimated execution cost does not establish that a stock will outperform.
What does Danelfin's AI stock score answer?
Danelfin's AI scores are designed to help compare stocks by an estimated probability of beating the market. That makes a score relevant to a stock-comparison question: how does one stock look relative to others under the scoring approach?
“Beating the market” concerns relative performance over the applicable measurement period. It is not the same as estimating the bid-ask spread on an order, assessing whether an intended quantity is large relative to daily trading volume, or checking how a new position changes a basket's concentration. Nor does a probability express a guaranteed outcome.
To interpret any stock score responsibly, check the provider's current explanation of what the score measures, the benchmark and horizon it uses, and how the underlying probability is defined. Those details determine what a comparison can—and cannot—tell you.
What does PreTrAIde's pre-trade analysis answer?
PreTrAIde starts with an intended trade rather than a stock-ranking question. You build a basket with a side, quantity and execution conditions for each stock. Before placing an order, you run a PreTrade analysis; each analysis uses one analysis credit.
The result includes a GO, NO-GO or MODIFY verdict for the basket and for each line, alongside a success probability, risk assessment, suggested execution strategy and plain-language reasoning. The success probability is a model estimate constrained to 5%–95%. It is not a forecast of returns, a guarantee or investment advice.
PreTrAIde's quantitative layer estimates bid-ask spread, participation in daily volume and market impact. It also calculates daily volatility, one-day 95% value at risk (VaR), liquidity and data-quality measures, and basket-level breakdowns. Its AI layer reasons from those measures alongside recent ticker news and analyst ratings. Guardrails can correct an AI verdict that conflicts with the data, but only in a more conservative direction.
PreTrAIde is analysis software, not a broker, investment adviser or portfolio manager. The user decides what to do and places any trade through their own broker.
Why quantity can change a pre-trade assessment
A stock score describes a stock under a ranking method. A proposed trade adds another variable: how much you intend to buy or sell.
Consider a hypothetical stock trading 100,000 shares per day. An order for 500 shares represents 0.5% of that daily volume; an order for 20,000 shares represents 20%. The calculation is:
Order participation (%) = order shares ÷ daily shares traded × 100
The stock is the same, but the proposed order's participation is not. A larger order may face different estimated market impact and may require different execution conditions. Daily volume is a reference measure, not a promise that any particular quantity can be filled immediately or at a stated price.
Spread matters too. If a stock has a hypothetical $0.10 bid-ask spread, the quoted half-spread is $0.05 per share. Buying 1,000 shares at the ask rather than at the midpoint implies $50 of half-spread cost under that simplified quote, before market impact, fees or price changes. Actual fills can differ. PreTrAIde estimates spread using a liquidity-tier model with a volatility uplift and a one-tick floor; the estimate is not a live execution quote.
Why a basket needs more than individual stock scores
Even if every line looks acceptable on its own, its weight in the basket can matter. Suppose a hypothetical $10,000 basket holds $5,000 in one stock and $2,500 in each of two others. Its weights are 50%, 25% and 25%. Its Herfindahl-Hirschman concentration index is:
HHI = 0.50² + 0.25² + 0.25² = 0.375
On a 0–10,000 scale, that is 3,750. HHI measures how concentrated the weights are; it does not predict whether the basket will gain or lose value. PreTrAIde also reports breakdowns by country, sector, region, currency and market capitalization, making exposures visible alongside line-level assessments.
This is why “Which stocks score highly?” and “What does this specific basket look like before I trade?” can produce useful but different information. Neither answer substitutes for the other.
How should you use the outputs?
Read a Danelfin score as a stock-comparison measure, subject to its published definition and limitations. Read a PreTrAIde verdict as decision support for the basket and conditions submitted. GO does not mean a trade will succeed; NO-GO and MODIFY are not instructions to sell or replace a security.
If a PreTrAIde verdict is MODIFY, its optional “Let AI Modify” feature can rework the basket once per analysis without another credit, subject to constraints on changes and position weights. That produces a revised basket to review—not an order. After a verdict, users can also open a paper-trading simulation; it uses no real money.
For a hands-on look at the underlying concepts, PreTrAIde provides free, no-sign-up tools for trading costs, position size, portfolio concentration, VaR and a pre-trade checklist. These calculations help frame a proposed decision, but neither a stock score nor a pre-trade verdict removes uncertainty.
