The model researches the strategy — and remains part of the trading decision.
LLM Trading is designed for cases where you want the model to interpret market context instead of reducing the final method to fixed deterministic code. Start with instruments, clusters, chart examples and a research objective. The project keeps the research conversation, governing prompt, backtest evidence and later trading decisions connected to one strategy context.
The agent can inspect charts, compare winning and failing examples, propose a hypothesis, test it, explain where the hypothesis breaks and revise the strategy prompt for another historical replay.
From market evidence to an LLM strategy that can be replayed and traded.
Define what the model should investigate and which instruments provide tradable or contextual evidence. Hard Settings keep risk permissions and runtime behavior inside a fixed contract.
Ask the model to find common setups, compare regimes, inspect correlations, explain losing cases, flatten the equity curve or abandon a weak hypothesis and search for another method.
The active prompt captures the strategy assumptions and tells the selected GPT model how to interpret charts, open positions, manage risk and decide between trading actions.
During historical replay the model receives the allowed context and makes LLM trading decisions. Trades, PnL, reasoning and chart evidence become the next research input rather than only a score.
Backtest conclusions are fed into the next reasoning cycle. The model can identify weak assumptions, revise the prompt and run another replay while project history remains attached to the same workspace.
This is the defining feature of LLM Trading: the model is not only the strategy designer. It also interprets the current trading context when the agent is asked to make the next decision.
Use Chat as an active trading researcher, not a one-shot strategy generator.
Find a common setup in several charts
Give the project a group of instruments and ask it to identify a repeatable market structure rather than optimize one fixed rule.
OUTPUT: hypothesis → prompt → replay → evidence.Work on drawdown or curve smoothness
Ask why losses cluster in one regime, which assumptions create the drawdown and whether the method can be improved without destroying trade activity.
OUTPUT: revised hypothesis tested against the previous backtest.Reason across correlated instruments
Use multi-instrument context for relative-value, correlation or hedging reasoning while controlling which cluster members can trade and which remain context-only.
OUTPUT: synchronized decisions informed by cross-market context.Abandon a weak method and search again
If optimization exposes a bad thesis, return to research instead of forcing the same strategy family. The conversation can move back from optimization to discovery.
OUTPUT: a new research direction without losing project history.One workspace connects contract, research, strategy artifact and replay.

A representative workflow with 10 Chat turns, prompt compilation, one 90-decision replay and five optimization stages is approximately $4.59 on GPT-5.4 mini, $12.20 on GPT-5.6 Terra or $30.51 on GPT-5.6 Sol. This is an example, not a fixed quote; actual usage depends on context size, output and the number of LLM decisions.
Start with the market question. Let the project develop the method around the evidence.
Choose instruments or clusters, define the hard contract and use Chat to direct the research. The project keeps the strategy prompt, replay evidence and later LLM decisions in one continuous workflow.
