For trades to qualify for $0 commission, all trades must meet the following criteria:


Limit order that does not create an immediate match (in less than one second).

The stock price is trading at $1 USD or higher.

Order size must be a minimum of 100 shares.

Stocks must trade on NYSE, AMEX or NASDAQ.


Please visit our Pricing and Fees page for additional details.

It doesn’t matter if you are long or short, as long as you use a limit order to execute away from the market, and the stock is trading at $1 USD or higher in share price.

The rate is determined by the difficulty to borrow the stock on that day.

The fees can vary during the day depending on market conditions. Locate fees are charged only after the price for the locate is accepted.

If the locate shares are declined, then no fee is charged.

TradeZero is changing our Overnight Borrow (ONB) fee billing methodology on August 1, 2025. What is changing?

On August 1, 2025, we are changing how we calculate ONB fees, moving from billing on a trade date (T/D) basis to a settlement date (S/D) basis. This change better reflects industry practice and market mechanics.

· ONB fees were charged overnight at the end of the date when you opened a short position (T/D).

· Fees stopped the day you closed the short position (T/D).

 If you shorted on Monday and covered on Tuesday, you were charged one day of ONB (Monday only).

· ONB fees will be charged starting the day the short sale settles i.e., the business day after the day of the trade, referred to as the “settlement date” (S/D).

· Fees stop on the settlement date of the buy-to-cover trade i.e., the business day after you close the short.

 If you short on Monday and cover on Tuesday, you are still charged one day of ONB fees, however, you are charge for Tuesday instead of Monday.

This new billing methodology improves fairness, sustainability and better reflects actual market mechanics.


What does this mean for my Overnight Borrow costs?

The change is more about timing than absolute costs. Under the new model, you are charged based on settlement date quantities, not trade date quantities. However, 

, particularly when holding shorts overnight around weekends and holidays, particularly on Thursdays.

· Example 1: If you shorted on Thursday and covered on Friday, you were charged 

· Example 2: If you shorted on Friday and covered on Monday, you were charged for 

· Example 1: If you short on Thursday and cover on Friday, you are now charged for

 of ONB fees (Friday, Saturday and Sunday because your closing trade on Friday doesn’t settle until Monday).

· Example 2: If you short on Friday and cover on Monday, you are now charged 

The two examples above illustrate how the change from T/D basis to S/D basis 

 affect the number of days for which you are charged ONB fees. While it is net neutral, it is important to understand how this timing difference could affect your fees.

The new billing methodology will apply to all short positions held overnight starting August 1, 2025.

No action is required. The change will be applied automatically. You’ll see ONB fees reflected based on settlement dates in your daily statements starting August 1.

Short selling involves selling shares you don’t own with the intention of buying them back later at a lower price.

When you hold the short position overnight, we must borrow those shares on your behalf in order to deliver them on settlement to the person who bought them — and that comes at a cost. 

The ONB is a fee charged by brokers to cover the cost of borrowing those shares

 from the market while your short position remains open.

Will I be charged an ONB fee if I short and cover the same day?

No. When you open and close a short position on the same trading day, there is no settlement obligation the next day as your buy and sell offset. Since no borrow occurs, no borrow fee is charged.
