What does each verdict mean?
In PreTrAIde, you build a basket of one or more stocks. For each line, you specify whether you intend to buy or sell, the quantity and execution conditions. A PreTrade analysis then evaluates the proposed basket before any order is placed.
| Verdict | How to read it | What to check next |
|---|---|---|
| GO | The proposed trade passes the analysis under the conditions assessed. | Read the risks, probability and execution suggestion; GO is not an instruction to trade. |
| NO-GO | The analysis identifies a reason not to proceed with the proposal as submitted. | Read the line-level and basket-level reasoning to understand the constraint. |
| MODIFY | The proposal has an issue that may be addressed by changing the basket or its execution conditions. | Identify what would need to change, then assess the revised proposal on its own terms. |
These are verdicts on a proposed trade, not labels declaring a stock good or bad. Quantity, other positions in the basket and execution conditions matter. A stock can raise a manageable issue in one proposed basket and a more serious one in another.
Read the stock and basket verdicts together
PreTrAIde returns a verdict for each stock line and for the basket as a whole. The distinction matters when the question is, “Should I buy this stock?” A stock-level result addresses that proposed line; the basket-level result also considers how the lines fit together.
For example, in a hypothetical basket, a proposed US$1,000 buy might have a GO at the line level, while the basket receives MODIFY because one position accounts for too much of the proposed basket. Conversely, a basket-level explanation can point you to a particular line whose liquidity or execution conditions need attention. Read both levels rather than treating one verdict as a substitute for the other.
The analysis includes 0–100 liquidity, volatility and execution scores for each stock and the basket. These scores provide context for the verdict; they are not expected returns. PreTrAIde also provides portfolio breakdowns by country, sector, region, currency and market capitalization, and calculates a Herfindahl-Hirschman concentration index (HHI). Those measures help show whether a concern belongs to one order or to the composition of the proposed basket.
What does the success probability mean?
The displayed success probability is a model estimate between 5% and 95%. It is not a guarantee, a forecast of investment returns or the probability that a stock’s price will rise. Read it alongside the stated risks and reasoning, not as a standalone answer to whether you should buy or sell.
A probability of 70%, for example, does not mean a hypothetical US$10,000 position is expected to earn US$7,000, or that seven out of ten future trades will make money. Those are different claims. The estimate is part of PreTrAIde’s assessment of the proposed trade; it does not quantify a future profit or eliminate uncertainty.
The range itself is worth noticing. PreTrAIde limits displayed probabilities to 5%–95%, rather than presenting 0% certainty or 100% certainty. Even a relatively high estimate does not override a risk you cannot accept or an execution condition you cannot meet.
What is in the risk assessment?
The risk assessment gives reasons behind the verdict. Three useful categories to distinguish are:
- Market and volatility risk: How much the stock’s price may move over the relevant period. PreTrAIde estimates daily volatility using blended methods and calculates one-day 95% value at risk (VaR). VaR is a model-based loss threshold, not a maximum possible loss: a hypothetical one-day 95% VaR of US$200 does not rule out a loss greater than US$200.
- Liquidity and execution risk: Whether the proposed quantity may be costly to trade relative to available liquidity. PreTrAIde estimates bid-ask spread, participation in daily trading volume and market impact. These are estimates, not a promise of the price or cost your broker will obtain.
- Concentration risk: Whether a line takes up a large share of the proposed basket or whether the basket is heavily exposed to particular countries, sectors, regions, currencies or market-capitalization groups. HHI and the largest position weight offer different views of concentration.
These risks are related but not interchangeable. A stock can have substantial price volatility yet be relatively liquid for a small proposed order. A less volatile stock can still present an execution problem if the proposed order is large relative to its trading volume. A basket can contain individually workable lines but remain concentrated overall.
PreTrAIde’s quantitative layer uses market data including end-of-day prices, volumes and company profiles. Its AI layer reasons from the quantitative scores, recent news and analyst ratings, then explains the result in plain language. Neither layer removes the need to check whether the information and assumptions suit your situation.
How should you read the execution strategy suggestion?
An execution strategy suggestion addresses how the proposed order might be approached, not whether a security will gain value. Start by comparing it with the quantity and execution conditions you entered. Then look at the estimated spread, volume participation and market impact to understand why execution may matter.
For a clearly hypothetical example, suppose a proposed US$10,000 order has an estimated spread cost of US$8 and estimated market impact of US$12. The combined estimated cost is US$20, or 0.20% of the proposed order value: US$20 ÷ US$10,000 × 100. Actual fills and costs can differ. The purpose of the estimate is to make an execution trade-off visible before you use your broker, not to predict an exact fill.
PreTrAIde does not receive, transmit or execute orders. You place any trade yourself through your own broker, where the available order types, live market conditions and final execution remain separate from the analysis.
What should you do with a MODIFY verdict?
Read what needs modification and why before changing anything. Is the concern the size of one line, the composition of the basket, or the proposed execution conditions? Check the per-stock reasoning against the basket-level reasoning so a change to one line does not leave the main concern unresolved.
A MODIFY is not a disguised GO. It says the submitted proposal has an issue that may be addressed; it does not say that every possible revision is acceptable. If you revise a basket, evaluate the revised quantities, lines and conditions rather than carrying over your interpretation of the original result.
PreTrAIde also offers Let AI Modify after a MODIFY verdict. Once per analysis, at no additional analysis credit, it can rework the basket through up to five AI passes that trim, exit or replace lines. It can add at most two new lines, keeps at least half of your original lines and limits any single position to 40% of the basket. Those are constraints on the automated modification, not assurances about investment outcomes. Review any proposed changes yourself before deciding whether to place an order.
How do guardrails affect an AI verdict?
PreTrAIde applies guardrails when AI output contradicts the data. A suspended stock is always NO-GO. A GO paired with a success probability below 50% is downgraded. Displayed probabilities are clamped to the 5%–95% range.
Guardrails only move a verdict in the conservative direction: they can prevent an overly permissive result, but they do not turn a cautionary result into GO. They are checks on the output, not proof that an assessment is complete or that a trade is safe.
A decision-support answer, not a recommendation
Pre-trade analysis helps organize questions that a simple “should I buy this stock?” prompt can miss: What exactly is the proposed order? How large is it relative to trading volume? What might execution cost? What does it add to the basket’s concentration? Which risks explain the verdict?
PreTrAIde is analysis software, not a broker, investment adviser or portfolio manager. A GO, NO-GO or MODIFY is a structured assessment of the basket you submitted—not personal investment advice, a direction to buy or sell, or a prediction of returns. The decision to trade, change the proposal or do nothing remains yours.
