How do you choose an AI trading platform?
The short answer
Ask seven questions of every candidate: Where does my money live? Who makes the decisions? Can I see the reasoning? How does it talk about losing? What maintenance lands on me? What does it really cost? And can I watch it work before paying it anything beyond time? Platforms that answer all seven cleanly are rare — which is exactly the point of asking.
Seven questions, and what the answers reveal
Question one — custody — is the eliminator: does my capital stay in my own brokerage account? Anything requiring deposits into the platform itself leaves the comparison immediately; that architecture is how the scam half of this category operates. Question two — autonomy — defines what you're actually buying: does the system decide and execute end to end, or am I the unlisted component who confirms alerts and closes positions? Be brutally honest about your availability during market hours; a semi-automated tool bought by a busy person is a subscription to missed signals.
Questions three and four probe character. Transparency: can I see why each trade happened — a log with reasoning — or is it a black box with a performance chart? Black boxes force a bad choice during drawdowns: keep faith blindly or quit blindly, and both are expensive. Risk honesty: read how the platform discusses losing. Real operators name drawdowns, publish risk disclosures, and cap their promises at process quality. If the marketing implies profits are a settled matter, the marketing has told you what the product is.
Questions five and six are about total cost. Maintenance: bot-builder platforms hand you strategy design, testing, hosting, and repair — a rewarding hobby, a poor fit for anyone wanting hands-off operation. Know which job description you're accepting. Pricing: flat subscriptions are predictable and independent of your results; percentage and per-trade models scale against you. Compute any fee against your realistic account size — a $249/month flat fee means very different things at $5,000 and at $100,000.
Question seven decides it: can I verify before I commit? The platforms worth considering let you run their real strategy on a paper account — live markets, actual decisions, zero capital — for as long as convincing takes. Then use it: watch a few weeks, judge the process through at least one rough patch, and only then size a live allocation. The platforms that can't offer observation are asking you to buy the one thing no one should sell: unverified trust.
The honest caveats
Availability decides the category
If you can't act during market hours, only full autonomy fits. The best semi-automated tool in the world doesn't work for someone in meetings at 10 a.m.
Fees compound like returns do
Model every pricing structure against your actual capital over a full year — including the months where results are flat or negative.
The paper test is non-negotiable
Any platform you can't observe before funding is a platform you're taking on faith. There are enough observable ones that you never have to.
One way to put a system on the problem — an autonomous quant AI engine trading US stocks and ETFs through your own brokerage.
Our answers, on the record
Custody: your money stays at your own brokerage — the engine connects through secure webhook bridges and never touches funds or credentials. Autonomy: full — the quant AI scans, decides, sizes, executes, and manages US stock and ETF trades end to end. Transparency: every decision logged with reasoning. Risk: disclosed plainly, including the CFTC-required statement in this page's footer; no return promises anywhere.
Maintenance: none on you — no strategy to build or infrastructure to keep alive. Pricing: flat $249/month for the autonomous plan, with a free trial. Proof: a paper account runs the identical strategy, so the seventh question answers itself — watch first, decide after.

Common questions
Promised or implied returns — 'members average X% monthly' and its cousins. In a risk-bearing activity, guaranteed outcomes are either dishonesty or misunderstanding, and neither should manage your money. Custody-taking (depositing into the platform) is the other immediate eliminator.
