Rules plus forecasts in one request

Ask what is true now and what is likely next about one symbol in a single call, and combine the two in code.

1. One request, both kinds

   Two rules, an English "now" question and three forecasts on MSFT:

2. The real response

   Session of 2026-10-30:

   {
     "model": "ora-fin1",
     "answers": {
       "trend": {
         "type": "yes_no",
         "yes_no": 0.9463,
         "rule": "C > sma(C, 200)",
         "basis": "rule"
       },
       "pullback": {
         "type": "yes_no",
         "yes_no": 0.7427,
         "rule": "C < sma(C, 20)",
         "basis": "rule"
       },
       "oversold_en": {
         "type": "yes_no",
         "yes_no": 0.0557,
         "rule": "rsi(C, 14) < 30",
         "basis": "comparison",
         "explain": "rsi < 30"
       },
       "up_week": {
         "type": "yes_no",
         "yes_no": 0.574
       },
       "drop5": {
         "type": "yes_no",
         "yes_no": 0.422
       },
       "rally5": {
         "type": "yes_no",
         "yes_no": 0.495
       }
     },
     "usage": {
       "input_tokens": 445,
       "output_tokens": 24
     },
     "context": {
       "source": "server",
       "symbol": "MSFT",
       "as_of": "2026-10-30"
     },
     "version": "ora-fin-0.1.1"
   }

3. Tell them apart

   Answers with rule are facts (trend 0.9463, pullback 0.7427, oversold_en 0.0557); the rest are forecasts (up_week 0.574, drop5 0.422, rally5 0.495).

4. Combine in code

   a = {k: v["yes_no"] for k, v in data["answers"].items()}
   setup = a["trend"] >= 0.6 and a["pullback"] >= 0.6     # facts: is the setup there?
   if setup and a["up_week"] >= 0.55 and a["drop5"] < 0.6:  # forecasts: act on it?
       signal("buy_the_pullback")
   elif a["drop5"] >= 0.7:
       signal("stand_aside")

   On this session the code above returns buy_the_pullback for MSFT: trend 0.9463, pullback 0.7427, up_week 0.574, drop5 0.422.

5. Why one request

   One round trip, one market-data fill and one bill for six answers, and every answer is about the same session, so the facts and forecasts cannot drift apart.

Information, not investment advice. Every number on this page is a real response for the session shown; answers change with each session.
