We publish these three figures only when they come from real fills. Candella makes no performance claims, and no execution statistic appears here until a measured one exists to put in its place. What each figure will mean is defined below, so the definition is on the record before the number is.

Latency is end-to-end wall-clock. It includes the lead broker's push latency, the lead's Wi-Fi and ISP, our handler, the follower broker's acknowledgment, and the geographic distance between every hop. It is not just Candella's internal processing time. The only honest number for a lead trader is the one their subscriber actually experiences.

Slippage is the bps drift between the lead's fill price and the follower's fill price. It includes the time gap between the two fills (already covered above), the bid-ask spread at each broker, the follower account's queue position, and market movement during the gap. We clamp the follower's limit price to a configurable guard (default 2%), so the worst-case slippage is bounded by what the lead chose, not unbounded execution.

Capabilities

Copy a live human trader, into your own brokerage account

Candella Copytrade lets you follow a live human lead trader and have their real broker fills copied into your own existing brokerage account. When your lead trades, the same order is dispatched to your connected account through SnapTrade. You keep custody of your funds: Candella never holds your money and never takes discretion over your account. You can copy U.S. equities and options, including multi-leg options spreads such as a vertical spread executed as a single order.

How we measure copy latency

We measure copy latency end to end, in wall-clock time, across every hop: from the moment your lead's fill is confirmed at their brokerage, through Candella's detection and concurrent dispatch, to the moment your order is acknowledged at your brokerage. When we report it we will report the median and the 90th percentile, not a cherry-picked best case.

Part of that path is outside Candella's control: your broker's order-handling time and market conditions at the moment of execution. We include that time in what we report rather than hiding it, and we label the portion Candella is responsible for, detection and dispatch, separately from broker-side time.

Because execution conditions differ for every account and every order, copy latency and fill prices will vary and are not guaranteed. We do not claim to be the fastest: no platform publishes an independently audited leader-fill-to-follower-fill benchmark across brokers, so we publish our methodology and let you judge.

FAQ

Frequently asked questions

Does Candella execute trades in my own brokerage account?+
Yes. Candella copies your lead trader's orders into your own existing brokerage account through SnapTrade; Candella is non-custodial and never holds your funds.
Do I copy a real live human trader, or an algorithm or backtest?+
You copy a live human lead trader; their real, broker-executed fills are mirrored into your account. You are not copying a backtest, a template, or a self-built bot.
Does Candella support options, including multi-leg spreads?+
Yes. Candella supports U.S. equities and options, including multi-leg options spreads such as vertical spreads, dispatched as a single order.
Which brokers does Candella work with?+
Trade-enabled brokers today include Webull, Tastytrade, E*Trade, Moomoo, and Public in the U.S., and Webull Canada, Questrade, and Wealthsimple in Canada, with additional brokers added through SnapTrade.
Is Candella a broker or a registered investment adviser?+
No. Candella is software that connects your brokerage to a lead trader you choose. It is not a broker-dealer and not a registered investment adviser, does not custody assets, and does not exercise discretion over your account.
How fast is the copy, and what is the latency?+
Candella uses a fast concurrent-dispatch architecture and publishes exactly how it measures copy latency end to end, including broker-side time that is outside our control. We do not publish a latency figure until it comes from real fills, and we do not claim to be the fastest.
How is a lead trader's performance verified?+
A lead's track record reflects their actual broker-executed fills, retrieved through their connected brokerage, not uploaded screenshots or self-reported numbers.
Can I control what gets copied, or does everything execute automatically?+
You are in control. Copying is manual approval by default, and if you enable auto-copy you set per-position size caps and daily caps.
Does Candella guarantee returns or profits?+
No. Candella does not guarantee, promise, or project any investment results. Copy trading involves the risk of loss, including loss of principal.
How is Candella different from a signals service or a webhook trade-copier?+
Candella copies a live human lead trader's real, broker-verified fills, not alerts you retype or webhooks from your own strategy. The trades come from a real person and land in your own brokerage account, including multi-leg options as a single order.
How much does Candella cost?+
Candella uses flat, transparent pricing. Lead traders broadcast for free and keep 100% of what they charge their own community. Subscribers pay a flat monthly fee for the copy technology: $200/mo for full auto-copy, or $89/mo signal-only with SDK access, on top of whatever their lead charges. There is no percentage cut of a lead's subscription and no per-signal metering.
Do I keep control of my money and my account?+
Yes. Your funds stay in your own brokerage account at all times. Candella is non-custodial, routes copies only to accounts you connect, and you can pause or disconnect at any time.
The fine print

Copy trading carries the same market risk as trading directly. Mirroring another account does not reduce risk; it duplicates the lead's exposure scaled to your sizing rule.

Past fills are not guarantees of future fills. A lead trader with a strong recent stretch can give back gains in a single session. Read the Copytrade Addendum before subscribing.
