Do you see my strategy code?

No. Strategies are stored in our self-hosted Postgres (we control the host, you control the data). We never read or share strategy logic, and live execution runs on your Bybit account using your API keys (encrypted at rest).

What exchanges do you support?

Bybit (USDT perpetuals + spot) is the live integration today. The architecture is exchange-agnostic — additional exchanges arrive when there's pull from paying customers.

How does loop mode work?

You describe what you want, pay one token, and the AI iterates the strategy up to ten times trying to find a +EV backtest. If it can't, you get the token refunded. The point is to outsource the reasoning, not gamble compute.

Why is Partner tier so small?

Partner ($999/mo) caps at 10 seats because it includes founder collaboration time. The product is identical to Starter — what scales exponentially is access to the person who wrote it. We'd rather under-promise founder time than overload it.

What about US users — can I pay with crypto?

Yes. NOWPayments handles crypto subscriptions in BTC/ETH/USDT and many others. We accept crypto specifically because some sellers are blocked by Stripe-network MoR rules, and we want anyone to be able to pay.

Selected layers — the DSL grammar specification and the chart engine — are documented; the backtest engine and live trading engine are not open source. The reasoning: open-sourcing the engines doesn't help users (they can't run them without our data layer + infra), and we want bug fixes to flow to paying customers first.

Self-hosted on our own hardware in South Korea, behind Cloudflare Tunnel. We migrated off Vercel/Supabase/Lambda in Phase 5-14 of our build because we want to own every layer of the stack.

OneTickTrading — every US crypto venue, one chart, your OS

The tax you've been paying

Your liquidity is split across exchanges. Your chart shouldn't be.

Coinbase trades BTC at one price. Kraken at another. CME front-month carries basis. When your charting platform shows you a single venue, you're looking at one corner of a market that's actually living on four — and that costs you in fills, in signal quality, and in opportunities you never see.

OneTickTrading pulls live ticks straight from each venue, time-aligns them, and renders the unified tape on one chart. Cross-venue basis becomes a signal you can read. Every print is venue-tagged. You stop trading one leg of a four-leg market.

Same minute. Four venues. Different prints.

OTT (stitched)

One trace per venue. The thick one is OTT — every venue's prints stitched, time-aligned, on one chart.

How OTT compares

The platforms US crypto traders end up on. And what each one asks you to accept.

Most platforms force you to pick which compromise hurts least: a different OS, an extra subscription, a strategy language built for software engineers. Here's the short version.

	OTT	Sierra Chart	ExoCharts	Bookmap	Quantower	NinjaTrader
Native Mac & Linux	Both	Neither	Mac only	Mac only	Neither	Neither
Live crypto execution	Yes	No	No	Partial	Partial	No
Strategies without C++/C#/Java	Yes	No	No	No	No	No
Realistic backtest with slippage	Yes	Partial	No	Replay only	Replay only	Partial
Same code: backtest & live	Yes	No	No	No	No	No
One flat price, no add-ons	Yes	No	No	No	No	No

The number you ship · is the number you see

Same strategy. Three backtesters.

Pine Script+197%

Sierra Chart+118%

OTT (real)+12.3%

OTT fills only when price actually traversed.
OTT subtracts time-of-day spread per round trip.
OTT walks the historical depth book for slippage.

The other way your strategies bleed

A backtest that doesn't lie. So the number you ship is the number you see.

Pine Script makes great strategies look great. The problem is they keep looking great long after they should have stopped — because Pine fills you at prices you'd never actually get, ignores spread, and skips intra-candle movement entirely.

OTT models the real-market mechanics Pine skips: slippage per instrument, intra-candle fill ordering, time-of-day spread, walk-forward, Monte Carlo. The number the backtest shows is the number you'll see live. No surprises on day one.

On the OS you actually use

Mac. Linux. Windows. All native. All fast. All the same OTT.

Most platforms ship Windows-only and tell Mac users to run a virtual machine. That's the wrong answer to a problem the platform should have solved itself. I did the work so you don't have to think about it.

OneTickTrading runs natively on Mac (Apple Silicon included), Linux, and Windows from a single codebase. Same app, same speed, same workflow on every OS. It doesn't sit on top of a browser. It doesn't pause to update during your trade. It opens fast, stays fast, and stays out of your way.

What's shipped. What's next.

Honest about scope. No "coming soon" that means "in three years".

This is a founder-built product. Some pieces are production-grade today; others are on the public roadmap. Both are listed here. If a feature you need isn't shipped yet, you can either wait — or join at Pro / Partner and bump it up the queue.

Who's building this

JHK. Solo founder. On the line for it.

Solo trader at a multi-monitor desk, late evening, green candle charts climbing

I built OneTickTrading because every existing platform asked me to compromise: run Wine on Linux, pay $300/month for a Bookmap setup, learn three different programming languages for three different platforms, or accept that my backtests were quietly lying. None of those were acceptable answers.

This is solo-founder-built. I do the work — every venue integration, every fill-modeling decision, every detail of the chart — so when you open the app, it just works. No add-on marketplace. No data-fee maze. No "install this third-party plugin" loop. Open it, place a sim trade, run a backtest, ship it live.

If you sign up at Pro or Partner, you're hiring me as well as the product. I read every email. I take the calls. I personally port your Pine Script. That part of the offer scales with the slider below — and so does what I owe you.

Pricing

Pick your level. The further right you slide, the more I'm personally on the line.

The product is identical at every level. What scales is how much I (the founder) am directly invested in your trading: office hours, individual calls, custom strategy ports, dedicated time. Slide to where you actually want me.
