From an idea to a strategy you trust
Build and test in your browser or through Claude, with simulated practice orders. Live orders go from the PTQ app on your computer to your own broker.
Every screenshot here is the real app. Illustrations are labelled as illustrations.
What you need in front of you
A browser
Sign in at app.part-timequant.com. Nothing to install.
Claude, if you want to talk to it
Claude Desktop, claude.ai or Claude Code can connect to your PTQ account.
No broker account required
Practice orders are simulated inside PTQ and never sent to a broker.
A region we can serve
Checkout refuses payment if PTQ cannot legally operate in your region.
Step 01
Buy
$997 per year. One plan, full access.
Checkout runs through Stripe, so your card details never touch our servers.
Payment creates your access key. Without it there is no key and no access.
Step 02
Sign in. It is already yours.
Use the account linked to your PTQ licence.
Sign in with the email you paid with. The engine runs on our servers and is not available as a downloadable archive.
The builder, backtests, validation, practice trading and research loop all run in the browser.
Step 03
Connect Claude
An optional connection to the same hosted account.
Open Connect Claude and follow the setup for your client. Put the private connection link only in connector settings or the hidden terminal prompt, never in a chat, screenshot or shared document.
Requests and results travel to and from hosted PTQ. Claude can do what the browser does, within your licence, credits and PTQ checks. Revoke the connection any time in Connect Claude.
Step 04
Choose your market
Check what data is available before you build.
Pick an instrument and timeframe the data providers support. A listed market may not have every date range or a practice quote.
No broker connection is needed, so never put broker credentials in a prompt or support message.
Step 05
Write your first strategy
Plain language, no code.
Start fresh or from a template: when to buy, when to sell, how much and where to get out.
Set your practice risk limits and check the preview. A passing risk preview is not a passing backtest.
Step 06
Let the gates try to kill it
Test the rules and review the evidence.
PTQ fetches history from its data providers. Coverage varies by market, interval and date, and missing data stops the run.
Validation checks for overfitting and shows which gates passed or failed. A pass is evidence to review, not proof of future performance.
Step 07
Try a practice order
Preview an order with practice money.
Preview a practice order from a validated strategy. You confirm it, then it passes risk and portfolio checks.
Fills are simulated inside PTQ and recorded in the journal. No broker is involved, no real money moves, and practice does not reproduce real execution.
Step 08
Understand live trading
Installing a connector does not enable live trading.
Browser and Claude orders use practice money. Live trading is not available here.
Step 09
See what happened
Review the results before deciding what to test next.
Read the practice journal and review report next to the backtest and validation results.
The research loop tests variations within a credit budget. Validate a changed strategy again before you rely on it. Research is not unattended live trading.
When a run cannot proceed
Each stop gives a reason. Read it before you change the rules or try again.
Location block
Checkout stops the sale if we cannot legally serve your region.
Gate block
Failed or missing validation evidence blocks practice orders.
Risk block
An order that breaks your risk or portfolio limits is refused.
Price block
No usable quote, or a price past your limit, refuses the order.
Broker block
Hosted PTQ does not send orders to brokers.
Engine block
If the calculation service is down, there is no new backtest result.
