Zerodha Features on WebNotes

Bank account verification (penny drop) on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

The penny drop method is a bank account verification technique widely used by Indian financial services firms, including Zerodha, to confirm that an account number provided by a client actually belongs to that client and that the account is active and capable of receiving electronic transfers. The method involves transferring a small amount (typically one rupee) to the client’s declared bank account. The transfer response from the bank confirms the account’s validity and, crucially, returns the account holder name as registered with the bank, which is then matched against the name on the client’s KYC documents.

Bracket order discontinuation (historical)

Mon, 11 May 2026 00:00:00 +0000

Overview

A bracket order (BO) was an advanced intraday order type offered by Zerodha and several other Indian brokers that combined three linked orders into a single instruction: an entry order, a stop-loss order, and a target order. The three-legged structure allowed a trader to define the entry price, the maximum loss (stop-loss), and the desired profit exit (target) in a single order placement, with the bracket structure ensuring that once any one of the three legs executed (stop-loss or target), the remaining leg was automatically cancelled.

CDS/MCX product circle on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

Indian financial markets are divided into distinct regulatory segments, each governed by its own set of SEBI and exchange regulations, and each requiring specific regulatory approvals for both brokers and clients. At Zerodha, the “product circle” refers to the set of market segments a client’s account is enabled to trade in. By default, a Zerodha account is enabled for equity trading on the NSE and BSE – both the cash (equity delivery) and derivatives (equity futures and options) segments. Additional segments, specifically currency derivatives (traded on the NSE’s CDS segment and the BSE’s CD segment) and commodity derivatives (traded on the Multi Commodity Exchange, MCX), require separate activation.

eMandate on Zerodha (UPI and net-banking)

Mon, 11 May 2026 00:00:00 +0000

Overview

An eMandate is a digital authorisation given by a bank account holder to a financial services provider, authorising the provider to debit the account for a recurring payment up to a specified limit, on a defined schedule, for a defined purpose. On Zerodha, eMandates are primarily used for Systematic Investment Plan (SIP) contributions through the Coin mutual fund platform, enabling automatic monthly debits from the client’s bank account to fund ongoing mutual fund investments without requiring manual intervention for each instalment.

Family declaration on Console

Mon, 11 May 2026 00:00:00 +0000

Overview

The family declaration feature on Zerodha’s Console platform allows multiple Zerodha accounts belonging to members of the same family to be linked under a single declarant account. Once linked, the family members’ portfolios, profit and loss statements, and tax reports can be viewed in an aggregated format from the primary (declarant) account, while each member’s account remains legally and operationally independent.

The feature is designed for households where multiple family members – spouses, parents and children, siblings – each maintain individual Zerodha accounts but where the primary investor or financial planner in the family wants consolidated visibility over the household’s overall investment position without the administrative burden of logging into each account separately.

Idle funds policy on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha’s idle funds policy is the set of operational procedures by which the broker identifies and returns uninvested client cash to the client’s linked bank account after it has remained inactive in the trading account for a defined period. The policy implements SEBI’s client funds segregation framework, which requires brokers to maintain strict separation between client funds and broker funds, and which mandates the return of idle client balances to prevent brokers from using client cash for their own purposes.

Kill switch on Kite (F&O cooling-off)

Mon, 11 May 2026 00:00:00 +0000

Overview

The kill switch on Zerodha’s Kite platform is a voluntary self-exclusion feature that allows a trader to suspend all futures and options (F&O) order placement for a defined cooling-off period. When activated, the kill switch prevents the account from entering new F&O positions until the cooling-off window expires. The feature is designed to interrupt loss-chasing behaviour – the documented tendency of traders who have suffered significant losses to increase their risk-taking in an attempt to recover, often compounding losses further.

Liquid fund margin (Liquidcase) on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

Liquidcase is Zerodha’s integrated facility that allows traders to invest funds sitting idle in their trading account into liquid mutual funds through Coin, Zerodha’s direct mutual fund platform, and simultaneously pledge those liquid fund units as margin collateral for futures and options (F&O) trading on Kite. The facility addresses a structural inefficiency in retail F&O trading: cash held as margin in a trading account typically earns no return, while the same amount invested in a liquid mutual fund earns money market returns while remaining available as collateral.

Margin pledge mechanics on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

The margin pledge framework, introduced by SEBI through its September 2020 circular, fundamentally changed how retail and institutional clients use securities as collateral for futures and options (F&O) trading in India. On Zerodha, margin pledging allows a client to pledge eligible equity holdings held in their demat account as collateral margin, reducing or eliminating the need to transfer cash to meet F&O margin requirements.

Before the 2020 framework, brokers commonly handled securities-as-margin by transferring client shares to pool accounts or directly to the clearing corporation. The new pledge mechanism keeps securities in the client’s demat account while creating a formal charge over them through the CDSL or NSDL depository infrastructure. This distinction protects client ownership rights and reduces systemic risk arising from broker commingling of client assets.

Mutual fund pledging on Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha allows clients to pledge mutual fund units held in demat form – typically units purchased through Coin, Zerodha’s direct mutual fund platform – as collateral margin for futures and options (F&O) trading on Kite. This facility extends the margin pledge framework to mutual fund units, enabling clients to earn returns on their invested corpus while simultaneously using that corpus as collateral against F&O margin requirements.

Mutual fund pledging is distinct from the Liquidcase facility (which specifically targets liquid fund units as near-cash collateral) in that it covers a broader range of fund categories including equity-oriented funds, debt funds, and balanced funds. The haircuts and collateral margin treatment vary significantly by fund category, and equity mutual funds in particular are treated as non-cash collateral rather than cash-equivalent collateral.

Nominee process at Zerodha

Mon, 11 May 2026 00:00:00 +0000

Overview

Nomination is a legal facility that allows the holder of a financial account to designate one or more individuals who will receive the assets held in that account upon the account holder’s death. At Zerodha, nomination is available for three distinct account types that a client typically holds: the trading account (broker account), the demat account (held with CDSL or NSDL), and mutual fund holdings (managed through Coin). Each of these accounts has its own nomination registration, and a nominee registered for one account does not automatically become the nominee for the others.

Nudges and behavioural design in Kite

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha’s Kite trading platform incorporates a structured set of behavioural nudges – deliberate design interventions that surface warnings, disclosures, and friction at the point of order placement. These nudges draw on research in behavioural economics to slow impulsive decisions, encourage risk awareness, and align retail trader conduct with the disclosures that SEBI mandates. The nudge system became more prominent after SEBI issued its circular on investor protection through technological interventions, and Zerodha expanded the feature set as part of its broader commitment to what it calls “responsible trading.”

Power of attorney and DDPI transition

Mon, 11 May 2026 00:00:00 +0000

Overview

For most of the history of modern Indian securities markets, brokers obtained a power of attorney (POA) from clients as part of the account-opening process. The POA granted the broker broad authority to operate the client’s demat account, enabling the broker to debit shares for settlement of sale transactions without requiring the client to issue a separate instruction for each trade. While operationally convenient, the POA model created significant scope for misuse: brokers with POA access could, in principle, pledge or transfer client securities beyond the narrow purpose of settlement.

Zerodha and T+0 settlement (current rollout)

Mon, 11 May 2026 00:00:00 +0000

Overview

T+0 settlement refers to a securities settlement cycle in which a transaction executed on a trading day (T) is fully settled – with funds credited to the seller and securities credited to the buyer – on the same trading day, before market close or by end of the trading day. Following the completion of the T+1 settlement rollout across all equities in January 2023, SEBI initiated a pilot for an optional T+0 settlement window on the NSE and BSE.

Zerodha and T+1 settlement

Mon, 11 May 2026 00:00:00 +0000

Overview

T+1 settlement refers to a securities settlement cycle in which a transaction executed on a trading day (T) is settled – with securities delivered to the buyer and funds paid to the seller – by the end of the following trading day (T+1). India completed the transition from T+2 to T+1 settlement for equity shares on the NSE and BSE in January 2023, making it one of the first major markets globally to implement T+1 as the standard settlement cycle for all listed equities.

Zerodha clearing corporation flows

Mon, 11 May 2026 00:00:00 +0000

Overview

Every securities transaction executed through Zerodha’s Kite platform passes through a clearing corporation before settlement is completed. The clearing corporation sits between the buyer and seller in every trade, guaranteeing completion of the transaction irrespective of whether either counterparty defaults. For NSE trades, the clearing corporation is NSE Clearing Limited (NSCCL, formerly the National Securities Clearing Corporation Limited). For BSE trades, it is the Indian Clearing Corporation Limited (ICCL). Zerodha, as a broker, holds clearing membership (or uses a clearing member) to participate in these clearing and settlement flows.

Zerodha Pi discontinuation and migration

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha Pi was a Windows-based desktop trading application launched by Zerodha around 2015 as the broker’s primary advanced trading platform. Pi offered a more feature-rich environment than the web-based tools of the time, including integrated charting with advanced technical analysis indicators, strategy testing using AmiBroker integration, multi-window layouts, and direct market access features for more active traders. The platform was positioned as Zerodha’s answer to the institutional-grade desktop terminals used by professional traders, adapted for the retail client.

Zerodha tech stack and engineering philosophy

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha operates one of the highest-volume retail brokerage platforms in India, processing millions of orders daily across equity, currency, and commodity derivative markets. The technology infrastructure required to support this scale – handling order routing, real-time market data, position tracking, margin calculation, and settlement reconciliation for millions of concurrent users – represents a significant engineering challenge. Zerodha has been unusual among Indian financial services companies in publicly documenting many of its technology choices and engineering decisions through its engineering blog (zerodha.tech) and Z-Connect posts, providing transparency into its technical approach.

Zerodha's open-source contributions

Mon, 11 May 2026 00:00:00 +0000

Overview

Zerodha has been among the most active contributors to open-source software among Indian financial services companies, publishing client libraries, data tools, infrastructure components, and configuration management tools under open-source licences on GitHub. The open-source programme serves multiple purposes: it supports the ecosystem of developers who build applications using the Kite Connect API, it signals technical credibility to the developer community, and it reflects the company’s stated philosophy of contributing to the broader technology community.
