Not investment advice
Nothing published by Halt Strategy is investment, financial, legal, or tax advice, or a recommendation or solicitation to buy or sell any security. The content is general information about market mechanics. It takes no account of your objectives, financial situation, or risk tolerance.

Limits of the halt data
- Halt codes, durations, and reopening procedures are set by the exchanges and regulators, not by us. They vary by listing venue and can change without notice. Confirm current rules against the primary sources listed in our editorial policy.
- Data shown in the product interface may be delayed, incomplete, or — where explicitly labelled as sample data — illustrative only. Do not trade from it.
- No market data source is error-free. Timestamps, prices, and halt classifications can be revised after the fact by the exchange.
Limits of historical analysis
Past performance does not indicate future results. Backtested results are hypothetical, carry the benefit of hindsight, and do not reflect slippage, fees, borrow costs, order rejection, or the practical difficulty of getting filled in a reopening auction — the exact place where halt strategies lose money in reality.
Halted securities are disproportionately low-float, low-priced, and thinly traded. Historical samples of them are affected by survivorship bias: securities that were delisted or suspended out of existence are the worst outcomes, and they are the ones most likely to be missing from any dataset.
Your responsibility
You are solely responsible for your own trading decisions and for evaluating the merits and risks of any security. Trading equities, and particularly halted or halt-prone securities, involves substantial risk of loss and is not suitable for every investor. You can lose more than you expect, and during a halt you may be unable to act at all — stop orders do not execute against a market that is not trading.
Consider seeking advice from a licensed financial professional who knows your circumstances.
