Day trading on margin

Margin allows traders to amplify their purchasing power to take advantage of larger positions than their cash positions would otherwise allow. By borrowing money from their broker to trade larger sizes, traders can magnify both returns and potential losses. Day trading involves buying and selling the same stocks multiple times during trading hours in the hope of making quick profits from the movement in the stock price. Day trading is risky because it depends on fluctuations in stock prices on any given day, and can result in substantial losses over a very short period.

Margin and Day Trading

Margin buying is a tool that makes trading easier even for those who do not have the necessary amount of money. Buying on margin increases the purchasing power of a trader by allowing him to buy for an amount greater than that for which he has cash; the deficit is made up by an interest brokerage firm.


When these two instruments are combined in the form of day trading on margin, the risks are increased. And as the saying goes “the greater the risk, the greater the potential return”, the returns can be many. But beware: there is no guarantee.

The rules of the Financial Sector Regulatory Authority (FINRA) define a daily transaction as “buying and selling or selling and buying the same security on the same day in a margin account”. Short selling and buying to hedge the same shares on the same day as well as options are also within the scope of a day trade.


When it comes to day trading, some do it only occasionally and would have margin requirements other than what can be termed a “day trader pattern”. We understand these terms as well as the rules and margin requirements of FINRA.


The term pattern daily trader is used for someone who executes four or more daily trades within five business days, provided that one of the following two things:

The number of daily trades is greater than 6 % of his total transactions in the account on the sidelines during the same five-day period.

A person makes two daily unfulfilled business calls within 90 days. The account of a day trader without a template only occasionally engages in day trading.

However, if any of the above criteria are met, a non-compliant day trader account will be referred to as a model day trader account. But if a model day trader’s account has not traded daily for 60 consecutive days, its status is reset to a non-model day trader account.

Margin Requirements

To trade on margin, investors must deposit sufficient cash or qualifying securities that meet the initial margin requirement with a brokerage firm. Under Fed regulation T, investors can borrow up to 50% of the total purchase cost on margin, with the remaining 50% placed by the trader as an initial margin requirement.

Margin Calls A margin call occurs if your account falls below the maintenance margin amount. A margin call is a request from your broker to add money to your account or close positions to bring your account back to the required level.

If you do not respect the margin call, your brokerage firm can close all open positions to bring the account down to its minimum value. Your brokerage firm can do this without your approval and can choose which positions to liquidate.

In addition, your brokerage firm may charge you transaction fees. You are responsible for any losses incurred during this process and your brokerage firm may liquidate enough stocks or contracts to exceed the initial margin requirement.


Although intermediaries must operate within parameters issued by regulatory authorities, they have the right to make small changes to requirements called “internal requirements”. A broker can classify a client as a day trader model, which fits it within the broader definition of a day trader model. Additionally, brokerage firms may impose higher margin requirements or limit purchasing power. Therefore, there may be variations depending on which broker you choose to trade with.

The Bottom Line

Day margin trading is a risky exercise and should not be tried by beginners. People experienced in day trading should also be careful when using margins for the same. Using margin gives traders greater purchasing power; However, it should be used with caution for day trading so that traders do not end up suffering huge losses. Limiting yourself to the limits set for your margin account can reduce margin calls and therefore the need for additional funds. If you are trying day trading for the first time, do not experiment with a margin account.
