Getting Started guide

Start with AI. Learn by iterating.

The fastest way to get value from MesoSim is to describe a trade idea, let the Integrated MesoSim AI Assistant draft it, run the backtest, and then use Ask AI on the finished run to analyze and decide what to test next.

auto_awesome You do not need to learn the whole Strategy Definition up front. Use AI to get to a runnable draft, then tighten it with the editor and analytics.
Recommended process
AI-first workflow
Starter prompt
Build an SPX Put Broken Wing Butterfly at 10 / 15 / 18 deltas at 60 DTE. Hold it for 30 days. Set Profit Target to $200, Stop Loss to $400
data_object
Start in JobEditor
Ask for a draft, a refinement, or a clearer version of the current idea when you want to move faster.
play_circle
Execute the backtest
Run the strategy once you are comfortable with the current structure so you can learn from real output instead of guessing.
query_stats
Ask AI on the finished run
Use it for run analysis, event summaries, and next-iteration ideas after the backtest completes.

Three AI surfaces, three roles

The assistant is built into the workflow. Pick the surface that matches the stage you are in.

data_object
Preferred start
Develop with AI

Start here when you want to develop a new strategy or modify a built-in template with the help of AI.

Ask something like
Create a 30 DTE Put Vertical Spread on RUT with 15 delta shorts, 10 delta longs and hold it for 10 days.
analytics
Analyze
Ask AI on a run

Open a finished backtest when you want the assistant to explain outcomes, summarize event behavior, or propose the next experiment.

Ask something like
Which position had the largest drawdown in this run, and what is the highest-signal change I should test next?
assistant
Knowledge retrieval
AI Assistant

Use this when you want quick help with generic MesoSim questions, capabilities or product behavior.

Ask something like
How does MesoSim handle profit targets and stop losses?

Can I exit a position based on the position delta?
Use AI where it helps
What the assistant is good at
edit_note
Draft new strategies from plain English
Describe the trade you want to test without starting from raw schema fields.
sync_alt
Refine the current JobEditor JSON
Keep the structure, adjust exits, repair errors, or ask for a more precise revision.
rule
Explain selectors, fields, and strategy conditions
Use it to bridge from intent to correct schema, not as a substitute for final review.
query_stats
Analyze completed runs and point to the next experiment
Ask about drawdowns, Sharpe, event behavior, or the single highest-signal change to test next.
Use docs second
Open docs when you need exact reference
  • Exact schema and field semantics
  • Built-in strategy ideas and reference material
  • Long-form walkthroughs and videos
  • Fast lookups with the Docs button and ⌘+K
Guardrails
Always verify
  • Read the generated Strategy Definition before you run it.
  • Use Event Viewer, the equity curve, and risk views instead of trusting the first draft.
  • Change one thing at a time between runs so the next result is interpretable.
Access and limits
  • You must be signed in and have an active plan to use the Integrated MesoSim AI Assistant.
  • Integrated MesoSim AI Assistant usage quotas with reasonable use apply.
  • Run-specific Integrated MesoSim AI Assistant questions only work on your own backtests.
  • For the free-to-use ChatGPT Hosted MesoSim AI Assistant, please use the ChatGPT Hosted MesoSim AI Assistant.

Reference

Keep the classic workflow nearby for exact docs, tutorials, and the pre-AI path, but do not make it your primary starting point anymore.
