An "All or None" (AON) order will stay unfilled both at the stock exchange and within the order system until the complete desired quantity of shares is available.

This order is initially submitted to the exchange as a pre-trade order, utilizing the calculated opening price. Should the order fail to execute, it will be re-submitted either as a fresh limit order or be transmitted to the market with improved bid/ask prices.

Under certain conditions, this order will be sent to the price improvement auction at the Boston Stock Exchange, adhering to their price and volume guidelines.

This algorithm assesses the impact of an option order on the market, effectively managing the risk of price fluctuations during the order's execution. Moreover, the system incorporates the user-defined urgency/risk factor and the maximum percentage value of the daily volume.

Numerous diverse orders are stored together in a single file and then transmitted as a bundle.

A limit order with a substantial volume, where the minimum order size is set at 50 contracts.

An automatic market order that converts into a limit order if it is not executed immediately at the market price.

This order is designed to restrict potential losses and safeguard profits. Each order is accompanied by both a stop and limit order, with the same quantity as the original order, to either supplement or restrict its execution.

This order will be executed once the market reaches the specific price range you have specified.

A discretionary order is a type of limit order where you predefine a specific amount that extends the execution range for the corresponding quantity. Execution is only possible after the discretionary amount has been considered. However, at the market, only the original limit price is visible.

A Fill or Kill (FOK) order must be executed immediately on the market as soon as it becomes available; otherwise, it will be instantly removed.

A Good After Time (GAT) order is initially held by the system and subsequently sent to the market at a user-defined date and time.

The Good 'Til Cancelled (GTC) order remains in the market until it is either executed or manually removed by the trader at a specific date, usually at market close.

The Good 'Til Date (GTD) order remains in the market until it is either executed or expires on a specific date, typically at market close.

A hidden order, typically with a high order volume, cannot be deduced from the market data or the order book.

An Iceberg or Reserve order allows you to submit an order, usually with a large order volume, that is not entirely visible on the market.

Any portion of an IOC (Immediate or Cancel) order that is not executed as soon as it reaches the market will be instantly deleted.

A limit order is an instruction to buy or sell a share at a predetermined price.

An LIT order is a specific type of order used to buy or sell contracts either below or above the current market price. This order remains in the system until the trigger price is reached, at which point it is then sent to the market as a limit order.

An LOC (Limit on Close) order is executed if the closing price is equal to or better than the specified limit price of the order, provided that it is supported by the respective exchange. If the condition is not met, the order will be deleted.

A LOO (Limit on Open) order is a type of limit order that is executed when it reaches the specified limit price or a better price at the beginning of the market session.

A market order allows a trader to buy or sell at the best price currently available in the market.

An MIT (Market If Touched) order is a type of order used to buy or sell securities either below or above the current market price. This order remains in the system until the trigger price is reached, at which point it is then sent to the market as a market order.

A market order that is executed to achieve a price as close as possible to the closing price of the day.

A market order that is automatically sent at the beginning of the market session and is executed at the prevailing price.

An MTL (Market to Limit) order is initially submitted to the exchange as a market order. In case of partial execution, the remaining portion of the order is first canceled and then re-submitted to the market as a limit order. The limit price for this new order is set to be the same as the price at which the executed portion of the order was filled.

An MWP (Market with Protection) order is a type of market order that, if not executed at the market price, is immediately canceled and re-sent as a limit order. The limit price is determined by the exchange and is set to be close to the current market price, slightly higher for a sell order and lower for a buy order. This mechanism offers protection against unfavorable price fluctuations when the market order cannot be executed at the desired price.

An MPM (Midpoint Pegged to Market) stock order will be executed only at the midpoint between the bid and ask prices in the market.

If an order that belongs to a group of One-Cancels-All orders is executed, all other orders in the same group are deleted.

An order specialized in buying at the best available bid price and selling at the best available ask price.

An order designed to automatically adjust the option price when the share price changes, according to the specific instructions provided by the clients.

This algorithm allows you to participate with a predetermined percentage of the total exchange trading volume.

A relative order derives its price from a combination of the market price and an offset amount specified by the customer. Initially, the order is sent as a limit order and subsequently adjusted based on the price strategy until it is either executed or canceled by the customer.

Option price request for Non-US options, futures and options and futures.

The scale order direction automatically generates a series of buy (or sell) limit orders, with each order having decreasing (or increasing) prices, in relation to the client's original limit order.

A spread order is a trading strategy that combines multiple individual orders, known as "legs," into a single cohesive trade. This strategy may include a combination of stocks, options, and future legs, forming a unified spread.

A stop order is an instruction given to a broker to buy or sell shares once the price crosses a predefined entry or exit point.

You can apply a one-time adjustment to a stop, stop limit, trailing stop, and trailing stop limit order to modify the stop trigger price, the trailing amount, and consequently, the stop limit price. This adjustment allows you to fine-tune the execution of these types of orders based on your specific preferences and market conditions.

A stop-limit order transforms into a limit order when the designated stop price is reached or surpassed. At that point, the order is executed as a limit order at the specified limit price or better.

A trailing stop for a sell order sets the stop price at a fixed amount below the market price, maintaining a certain distance.

‍

If the market price increases, the stop price moves up by the same trail amount, keeping the distance intact. However, if the market price decreases, the stop loss price remains unchanged.

‍

Trailing stops for buy orders operate in a similar manner, adjusting the stop price with the market movement but in the opposite direction.

A trailing stop-limit order for a stock sale sets the stop price using a fixed amount below the current market price and specifies a limit price for the order.

‍

As the market prices rise, the stop loss price is adjusted upwards by the same fixed amount. However, if the share price falls, the stop loss remains unchanged.

‍

When the order is triggered, a limit order is sent to the market at a strike price pre-defined by the customer. The same mechanism works in reverse for a trailing stop-buy order.

‍

A sweep-to-fill order identifies the best price and the exact quantity available at that specific price.

‍

The corresponding portion of the order is then immediately transmitted to the exchange for execution.

‍

Simultaneously, the next best price and the corresponding quantity available are identified, and the relevant part of the order is also transmitted without delay.

‍

This process continues until the entire order is executed. The goal of the sweep-to-fill order is to execute the trade as quickly as possible by capturing the available liquidity at different price levels.

‍

An order whose limit price of the option or the combination is determined as a function of the implied volatility.

The Volume Weighted Average Price (VWAP) for a share is calculated by summing up the products of the price and the number of shares traded in each transaction and then dividing by the total volume of shares traded.

‍

In the standard method, the VWAP order is computed from the market's opening to its closing by volume-weighting all transactions executed within this time frame.

‍

This algorithm aims to achieve the best possible Volume Weighted Average Price (VWAP) without surpassing the maximum percentage of the daily exchange trading volume, as defined by the user.
