Decide on a stock with just its symbol

Ask trading questions about a US stock or ETF without sending any market data: the server fills in the latest completed session.

1. Write the questions you trade on

   Plain English, one outcome per question, with a horizon: “Will the stock be higher in a week?”, “Will it drop at least 5% at some point in the next month?”, “Will volume spike tomorrow?”. Browse Examples → Financial for many more.

2. Send only the symbol

   Set state to {"symbol": "TSLA"} and leave out context:

   {
     "model": "ora1",
     "state": {
       "symbol": "TSLA"
     },
     "questions": {
       "up_week": {
         "type": "yes_no",
         "instructions": "Will the stock be higher in a week?"
       },
       "drop5": {
         "type": "yes_no",
         "instructions": "Will it drop at least 5% at some point in the next month?"
       }
     }
   }

3. Check which data was used

   The response adds "context": {"source": "server", "symbol": "TSLA", "as_of": "…"}: the session the answer is based on. Numbers are refreshed after each close (about 16:40 and 20:40 New York time); during the trading day you get the previous session.

4. Know the coverage

   About 2,000 liquid US stocks and ETFs. For anything else you get a 422 that says so; send your own numbers in state.context instead (see Ask by symbol).
