Tradejini · Tradejini CubePlus API v2
Tradejini copy trading, built on the CubePlus API
Link your Tradejini accounts, mark one as the parent, and every order it places is mirrored into the others with your own multiplier applied to each. Child accounts can sit at any supported broker.
Integration
How QuantGrid connects to Tradejini
QuantGrid connects to the Tradejini CubePlus API and watches a parent account by polling its order book several times a second, which is how every account here is watched and is the source of record even where a live feed exists. Orders are placed over the same REST API. Tradejini publishes two kinds of application: one you sign in to through its own page, and one that signs in unattended from your password and an authenticator code, so you can choose whether QuantGrid connects on its own each morning or you press Connect once a day.
QuantGrid watches your parent account by reading its order book several times a second over the CubePlus API. That is how every account here is watched and is the source of record even at the brokers that publish a live feed, so an order placed anywhere on the account is picked up, including one you place in Tradejini's own app.
Child orders go over the same REST API. Tradejini names an instrument by its own symbol id rather than by a trading symbol (an NSE Reliance holding is EQT_RELIANCE_EQ_NSE), so QuantGrid holds Tradejini's published instrument list and resolves every contract through it. Their list is public, which is unusual, and it means QuantGrid can identify a contract before anyone has connected an account.
- Equity and F&O on NSE, BSE, NFO and BFO
- Commodities (MCX) and currency (CDS and BCD) are not supported.
- Choose between signing in through Tradejini's own page once a day and letting QuantGrid sign in for you, which needs an authenticator app on the account rather than an SMS code
- All four order types copy to a Tradejini account, plain market orders included, which not every supported broker accepts
- Stop-loss market orders copy to a Tradejini account
- Instruments are addressed by Tradejini's own symbol ids, which QuantGrid resolves from their published instrument list
- Tradejini requires the address orders arrive from to be registered when you use the unattended sign-in, and it accepts an IPv4 address for it
- Order updates are read from the order book rather than a live feed. Tradejini's feed is a binary format only its own software libraries read, so QuantGrid watches by polling, which is a few seconds slower to notice an order and no less reliable
- Cross-broker replication: a Tradejini account can be a parent or a child

Connect Tradejini in three steps
Setup is a one-time job and usually takes a few minutes. Nothing is replicated until you explicitly link a parent to a child and save a multiplier.
- 01
Register an app in the Tradejini developer portal
Sign in with your CubePlus account, create an app, and copy the api_key and api_secret into QuantGrid. Choose the app type deliberately: an Individual App is the one that can sign in unattended and the one that asks for a static IP. Fill in your client ID too.
- 02
Register your dedicated address
QuantGrid assigns your account a dedicated static IPv4 address. Add it to your app in the developer portal, then press Log in now in QuantGrid. If the account looks signed out shortly afterwards, this is the likeliest cause: Tradejini answers a request from an unregistered address with the same bare Unauthorized it uses for an expired session, so the two look identical from the outside.
- 03
Link accounts and set your rules
Mark one account as the parent, add your child accounts, and set a copy factor, lot size and max quantity for each one. Replication starts on the next order the parent places.

Authorisation
Sessions, tokens and revoking access on Tradejini
Broker sessions are governed by the broker, not by QuantGrid. Here is exactly how that behaves so nothing surprises you at 9:15 in the morning.
Two kinds of application, and the choice is yours
Tradejini publishes an Individual App, which signs in unattended from your password and an authenticator code, and a User-Based App, which sends you to Tradejini's own page to sign in. QuantGrid supports both. The unattended one is what keeps a parent account connected without anyone at a screen; the other needs one click each trading day.
Unattended sign-in needs an authenticator app, not an SMS code
Tradejini accepts either as your second factor. Nothing running unattended can read your inbox, so an account on SMS or email codes has to use the sign-in page instead. Turn on an authenticator app in your CubePlus profile and copy the setup key into QuantGrid if you would rather it signed in for you.
Sessions last 24 hours
Tradejini states the lifetime rather than a fixed cut-off, and QuantGrid renews it for you on the unattended path. On the sign-in-page path you press Connect once a day.
One static IP, reserved to your account
Your API traffic leaves from a dedicated static IP address that is never shared with another customer. Where a broker lets you restrict API access to a whitelisted address, you have one stable address to whitelist, and your activity is never mixed with anyone else's. See the security practices.
Pairing
Running Tradejini alongside the other live brokers
A Tradejini account works as a parent or as a child, in any combination with the other supported brokers. Every order type this platform models reaches a Tradejini child in its own form, a plain market order included, with nothing substituted for it, which is not true of every broker here. Two things to plan around: it needs an IPv4 address, because Tradejini publishes no IPv6 address for its API at all, and order updates are read from the order book rather than a live feed, because Tradejini's feed is a binary format only its own software libraries read. That costs a few seconds in noticing an order and nothing in reliability, since the order book is what QuantGrid treats as the record everywhere.
Tradejini as parent
Drive children at any live broker
Orders placed in your Tradejini parent account replicate into child accounts at Tradejini, Zerodha, Angel One, FYERS, Groww, Motilal Oswal, Upstox, Nuvama Wealth, ICICI Direct, Dhan and Kotak, each with its own copy factor, lot size and max-quantity cap.
Tradejini as child
Follow a parent at another broker
A Tradejini account can equally be the follower. A parent at Zerodha or Angel One or FYERS or Groww or Motilal Oswal or Upstox or Nuvama Wealth or ICICI Direct or Dhan or Kotak drives it, with symbol and product-type translation applied automatically on every order.

Pricing
What Tradejini replication costs
One price per broker account you connect: its dedicated static IP, with every feature included. Tradejini needs IPv4, for the reason below. There is no platform fee, no per-child software surcharge and no share of anything you trade.
Dedicated static IPv4

The safe default, accepted by every broker API today.
The cheaper IPv6 address is not offered for Tradejini, because it would not work. Orders reach Tradejini at api.tradejini.com, which published no IPv6 (AAAA) record when we last checked it on 22 August 2026. An IPv6-only address cannot open a connection to an IPv4-only host, so every order would fail. Tradejini accounts need the IPv4 address above. See the dated reading for every broker.
