Tools & Calculators

Margin pledge, DDPI, and MTF are all gradually becoming essential parts in modern trading, especially for investors who wish for flexibility without selling their long-term holdings. These tools make it easier to access limits, trade efficiently, and manage capital with much more control. Given below is a lucid explanation of how each of these features works and why platforms like HDFC SKY are making them even more accessible.
Margin pledge allows an investor to use the value of their existing shares to create additional trading limits. Instead of liquidating shareholdings to raise funds, an investor may pledge them and unlock a usable margin that is based on what they already own. The broker decides how much margin to offer by applying a ‘haircut’.
The lower haircut provides more margin and generally indicates that the stock is considered safer. Higher margin percentages are given to well-established and liquid companies, which can often be between 70% and 85%. Riskier or volatile companies receive lower percentages.
The important point here is that the investors do not lose ownership of their shares. The holdings remain in the demat account, visible and available for sale at any time. Only a pledge marks them as collateral. This margin can be used for:
However, pledged margin does not support delivery buying.
Another benefit is cost control. If the investor uses the pledged limit only for intraday F&O and closes the trade on the same day, there is no interest charge. As stated earlier, the interest only applies when the pledged margin is utilised to carry forward a position or borrow funds overnight.
Because CDSL processes instructions in real time, pledging works only during market hours. Once verified, the margin appears instantly.
Unpledging is equally straightforward:
Both pledging and unpledging carry a small ₹20 + GST fee per script.
DDPI is a digital authorisation that makes the selling and pledging of shares faster and more convenient. Prior to DDPI, each sell order needed a new CDSL OTP. This delayed the execution of trade and caused delays during rapid market movements.
After activating DDPI, investors won’t have to use OTPs for every sell order. The broker can debit the shares directly whenever the investor sells them. The same is done in pledging and unpledging requests.
DDPI ͏does not͏ give unrestricted access to the ͏broker.It is limited only to initiatives initiated by the investor through their own trading account.
DDPI has become essential for modern investors since it removes delays and makes selling, pledging, and unpledging so much easier.
In volatile markets, prices change in seconds. If you wait for a CDSL OTP every time you sell, then the OTP͏ delay can ͏cause you to lose the best exit price. With DDPI, orders are executed instantly without any additional confirmation, helping you act the moment the market moves.
Margin creation becomes tough when OTPs arrive late or not at all. DDPI removes this problem by allowing pledging and unpledging with a single tap. This ensures you get margin exactly when you need it for F&O, intraday or MTF without interruption.
Without DDPI, you have to switch between your trading app and SMS or email to fetch OTPs every time you place certain orders. This slows you down. DDPI eliminates this step completely, allowing you to complete actions inside the very same app without switching screens.
DDPI is SEBI-approved and Aadhaar-based, which means it uses biometric and OTP authentication during setup. It’s safer than the old POA, with only limited rights given to your broker, specifically for selling and pledging. Your holdings stay protected while your transactions become smoother.
DDPIs serve both long-term investors and active traders. Long-term investors can sell their shares quickly without having to go through repeated OTPs while day traders can instantly generate and release margin. Whether you trade once a week or every day, it makes all the trade actions fast, simple and efficient.
Enabling DDPI on HDFC SKY is completely digital and takes less than a minute.
Open the HDFC SKY app and go to your profile or account settings. There you will have a DDPI or Demat Authorisation option exclusively. This is where set-up happens, and it’s designed in a way to take you through the process without confusion.
From here, in the DDPI section, you will see a button labelled Enable DDPI. Tap on it to start the activation. Now the app will move to the verification stage.
The system uses your Aadhaar-linked phone number to verify your identity. You will need to type in this number, and the app will verify it instantly. This step ensures that only the real account holder can ͏activate DDPI.
An OTP is sent to your Aadhaar-linked number. Enter the OTP in the app to confirm the request. This ensures secure and authorized activation.
Finally, the app will show a consent page explaining what DDPI allows. After reading and approving it, tap Submit. Your DDPI instantly gets activated, and you can start enjoying faster and smoother transactions right away.
On completion, the DDPI becomes active instantly. You can then sell and pledge shares without entering multiple OTs.
MTF is fast growing in India because it enables investors to buy quality stocks without paying the full amount in advance. Earlier, MTF required heavy paperwork, but today, platforms offer instant activation and easy repayment.
More investors now use MTF for momentum trades, short-term holds, and systematic buying of strong companies.
MTF, or Margin Trading Facility, is a facility that allows you to buy stocks by paying only a part of the total amount while the broker finances the rest. It works like short-term financing for equity delivery. You continue holding the shares in your demat account, but they remain pledged until you clear the funded amount.
Interest is charged only on the portion financed by the broker, calculated daily. This gives you flexibility and full control over how much you want to borrow and for how long.
Interest is charged only on the amount that is funded, on a daily basis. Since the investor chooses how much to use, MTF gives flexibility and control.
Margin pledge plays a significant role in MTF. When an inves͏tor buys shares on MTF, the shares automatically get pledged. This serves a collateral for the broker.
This combination helps investors to take larger positions while keeping ownership and clarity over their holdings.
HDFC SKY offers a specialised research discovery section specifically for stocks that are suitable for MTF. It saves time and eliminates confusion regarding which shares are is eligible for MTF.
