Copy trading conversations tend to focus entirely on the software — the multiplier, the dashboard, the speed. The broker underneath gets mentioned only in passing, if at all, despite doing most of the actual work: holding your funds, executing every trade, and carrying the regulatory responsibility for the API connection the whole setup depends on. This article is about that side of the equation.
What Role Does the Broker Actually Play?
Your broker executes every trade, holds your funds and securities, and is the entity your copy trading software connects to — never the other way around. Copy trading software reads and places orders through your broker’s API; it does not sit between you and the exchange, and it does not custody assets. If a “copy trading” product ever asks you to deposit funds with it directly instead of your broker, that’s a fundamentally different, higher-risk model worth scrutinizing closely.
This isn’t just a practical detail — it’s also how SEBI’s regulatory framework is structured. Under SEBI’s February 2025 circular on algorithmic trading, “brokers shall be the principal while any algo provider or fintech/vendor… shall act as its agent” when using the broker’s API. In plain terms: the broker is accountable for the API relationship, must handle related investor grievances, and is expected to deal only with properly empanelled providers. We cover this framework in full in Is Copy Trading Legal in India?.
What to Check With Your Broker Before Copy Trading
| Check | Why it matters |
|---|---|
| Does your broker expose an API at all? | Not every broker does, and this is a hard requirement — no API access means no software-based replication is possible |
| Does it support API-key + TOTP authentication? | This is the standard, more secure authentication pattern most copy trading software expects, distinct from your everyday login password |
| Are there account-type restrictions on API access? | Some brokers gate API access behind specific account tiers or additional KYC/authorization steps |
| What do your broker’s own terms say about third-party order placement? | You’re authorizing a third party to place orders on your behalf — know what your broker’s terms require or restrict here |
| Is your broker actually integrated with the specific software you’re considering? | Integration is always a named list, not a universal guarantee |
Brokers BlinkCopied Currently Supports
As one concrete, current example, BlinkCopied documents integration with 12 Indian brokers:
| Zerodha | Groww | Angel One |
| Fyers | Dhan | Kotak |
| IIFL | Alice Blue | Shoonya |

This list will change as integrations are added or removed — always confirm current support directly on BlinkCopied’s website rather than relying on any static list, including this one.
Choosing a Broker With Copy Trading in Mind
If you’re choosing a broker specifically because you plan to use copy trading software, it’s worth adding a few criteria to the general broker-selection framework covered in BlinkCopied’s Academy lesson, How to Choose a Broker for F&O Trading in India:
- Confirm API availability before anything else — a broker can be excellent on every other dimension and still be unusable for software-based replication if it doesn’t expose an API.
- Check integration status with the specific software you intend to use, not just “does the broker have an API” in the abstract.
- Understand the broker’s own algo/API terms, since these govern what you’re authorizing beyond the software provider’s own terms.
- Everything else that applies to broker selection generally still applies — brokerage costs, platform reliability, and support quality don’t become less important just because orders are being placed via API.
Does Copy Trading Software Cost More Through Your Broker?
No — brokerage, DP charges, and other broker-side fees apply the same way regardless of whether an order was placed manually or replicated by software; your broker doesn’t know or care which. Copy trading software itself is typically a separate subscription paid to the software provider, on top of — not instead of — your normal broker charges. See BlinkCopied’s Pricing for one example of how that’s structured.
What to Verify Before Connecting
- Does your broker expose an API, and does the software you’re considering currently integrate with it?
- Are you authenticating with an API key and TOTP secret, not your day-to-day login password?
- Have you read your broker’s own terms on authorizing third-party order placement?
- Do you understand that your broker — not the copy trading software — holds your funds and remains legally responsible for your account?
- Have you confirmed current broker support directly with the software provider, rather than relying on an older list or a search result?
Frequently Asked Questions
Do all brokers support copy trading?
No. Copy trading software has to be technically integrated with each broker's specific API, so support is always a named, finite list — not a universal guarantee. Always check a specific provider's current supported-broker list before assuming your broker is included.
Is my broker still fully responsible for my trades if I use copy trading software?
Yes. Under SEBI's algorithmic trading framework, the broker is treated as the "principal" and any algo provider or fintech connecting through its API acts as its "agent" — the broker retains responsibility for risk management, investor grievances, and API access controls, regardless of which software is placing orders.
Does copy trading software need my broker login password?
Legitimate setups don't ask for your login password directly — they use your broker's official API key and, where applicable, a TOTP secret for two-factor authentication, which is a separate credential from your day-to-day login password.
Can I copy trade across two different brokers at once?
Yes, if the software you're using has integrated with both — a master account on one broker can, in principle, drive client accounts on a different broker, as long as both are supported and properly authorized. Verify this specific scenario with your provider rather than assuming it.
Does using copy trading software cost extra through my broker?
Broker-side charges (brokerage, DP charges, AMC) apply regardless of how an order was placed — manually or via copy trading software. Copy trading software itself is usually a separate subscription, paid to the software provider, not your broker.
What should I check with my broker before connecting copy trading software?
Whether your broker exposes an API at all, whether it supports the authentication method (API key, TOTP) the software requires, whether there are any restrictions on third-party API access for your account type, and what your broker's own terms say about authorizing third-party order placement.
Key Takeaways
- Copy trading software doesn't replace your broker — it connects to your broker's own API, and your broker remains where your funds, holdings, and legal account relationship sit.
- Under SEBI's framework, brokers are the "principal" and algo/execution providers act as their "agent" — brokers retain responsibility for risk management and investor grievances regardless of the software used.
- Broker support for any given copy trading tool is a specific, finite integration list — never assume compatibility without checking.
- Authentication should use your broker's API key and TOTP secret, not your everyday login password.
- Broker-side trading costs apply the same way regardless of how an order reaches your account — copy trading software is a separate cost on top, not a replacement for brokerage.
Conclusion
It's easy to focus entirely on the copy trading software and forget that the broker underneath it is doing most of the regulatory and custodial heavy lifting — holding your funds, executing the actual trade, and remaining accountable for how its API is used. Choosing copy trading software is really a two-part decision: does it do what it claims, and does your specific broker support it properly. Skipping the second question is one of the more common — and easily avoidable — mistakes people make when getting started.
