The problem
Stop guessing entries
You see a chart, a tip or a video and you jump in. Where's the stop? Where's the target? Did that idea ever actually work, or did it just look good on one chart?
Pai Trading turns that guesswork into a written plan and a tested rule, so you study the setup before you risk anything, and you see the failures as clearly as the wins.
Good fit if
- You want to learn rule-based trading before you risk money
- You want every idea to come with an entry, stop and target
- You care whether a rule survived an out-of-sample test
Not a fit if
- You want signals to copy with real money
- You want promises of a win rate or income
- You need a broker or automatic trading
Proof over promises
It shows you the rules that failed
Most scanner ads show winners. Pai Trading labels every rule that lost money out of sample, after costs, and keeps it off the scanner. You see exactly why a setup qualified: the plan, the conditions and the test behind it.
What we will never show you
- A win rate or a "profitable trades" list
- Income claims or "big winner" testimonials
- Countdown timers or fake discounts
Results depend on the rule, the market and you. Past and backtested results do not predict the future.
Why it helps
Everything a setup needs, on one screen
Scanner with printed plans
Each qualified buy or sell shows its entry, stop and targets, with the condition tally behind it. Later bars do not repaint the plan.
Out-of-sample backtests
Rules are scored after costs on the untouched last 30% of signals. A rule that fails is labelled, not hidden.
3D Pai Trading City
Every tower is one strategy on one symbol, its height is cumulative R. Tour it, flip to a flat map, tap a tower for details.
Custom screener
Filter Dow, S&P and other published indices by quotes, fundamentals and daily geometry, then read the same Quantum Cloud and Codex gates.
Position sizer + journal
Work out a position size from budget, entry and stop, and keep notes on what you studied. Nothing is sent to a broker.

How it works
3 steps
Scan
Open the scanner or screener and pick a market and timeframe. Qualified setups come with a printed entry, stop and targets.
Check the evidence
Look at the backtest and the City: did this rule hold up on data it never saw, after costs? If not, it says so.
Plan and note it
Work out the size on the desk, write what you saw in the journal and review what each test taught you on the Learned page.

FAQ
Questions about Pai Trading
Is this financial advice?
No. Pai Trading is an educational study tool. It does not tell you what to buy, does not guarantee results, and past or backtested results do not predict the future.
Does it place trades or connect to my broker?
No. It has no broker connection and places no orders. The desk only works out a size from the numbers you type, and the journal is for your notes.
What markets does it cover?
US and Canadian names, major FX pairs and crypto from named data sources. Quotes can be delayed and some data may be missing; missing data stays missing instead of being invented.
Is it part of the All Apps Pass?
No. Pai Trading is sold separately at $30 USD/month or $306 USD/year (Save 15% — $25.50/mo billed yearly). The $72/month All Apps Pass does not include it. Both plans start with a 7-day free trial on Gumroad. There is no lifetime or one-time option.
How does the free trial work?
Start your 7-day free trial on Gumroad. Cancel before it ends and you are not charged; otherwise your plan starts at $30 USD/month or $306 USD/year (Save 15% — $25.50/mo billed yearly).
How do I cancel?
Plans are Gumroad subscriptions that renew until you cancel. Cancel during the 7-day free trial and you are not charged. Cancel any time from your Gumroad receipt or library, or email paidigitalstore@gmail.com.
What devices does it work on?
It is a hosted web app: open it in a modern browser on desktop or phone and sign in with the email you used at checkout.
What if it is not for me?
Use the 7-day free trial to decide, and cancel before it ends if it is not for you. After a paid charge, our refund policy covers purchases that are corrupt or materially misrepresented: email paidigitalstore@gmail.com within 7 days.
