The Open API SDK encapsulates the underlying interfaces that Tiger Brokers offers, providing a convenient way for our users to trade, monitor and manage their accounts in their self-designed trading programs, using programming languages of their choice(Java/Python/C++/C#).

Open API now supports the following order types:

  • Open API now supports the following order types:
Order TypeDescription
Market OrderRefers to an order that does not require the customer to set a price and will be executed at the latest market price after placing the order. Market orders can result in quick execution but do not guarantee the execution price. During rapid market changes or for inactive stocks, market orders may be executed at a higher or lower price. Please evaluate the relevant risks carefully before placing an order.
Limit OrderRefers to an order that requires the customer to specify the execution price and will only be executed when the stock price reaches the specified price or a better price. Limit orders will only be executed at the limit or better than the limit price, effectively locking in the trading price range. However, using limit orders may result in missed opportunities if the stock price does not reach or fall to the limit price, and the order will not be executed.
Stop Loss OrderRefers to an order that automatically submits a market order when the stock price reaches or exceeds the stop price set by the customer, depending on the direction of the buy or sell selected by the customer. It serves to protect profit or limit losses. A successful order placement or a market order placement after the stock price reaches the stop price does not represent or guarantee the successful execution of the stop loss order. If there is insufficient buying power or positions in your account, subsequent market order placements may fail.
Stop Limit OrderRefers to an order where the customer sets a stop price and a limit price. Once the stock price reaches the set stop price, the order will be placed as a limit order. This type of order can be placed as a limit order to avoid significant deviation from the customer's expected stop loss price. However, if the price rapidly drops below the limit price and continues to decline, the order may not be executed, and the loss will continue to expand. Please note that some underlying assets do not support stop-limit orders.
Trailing Stop OrderRefers to an order that allows customers to set a trailing amount or percentage so that the stop loss trigger price can be automatically adjusted based on market price fluctuations. When the market price reaches the stop loss trigger price set by the customer, the system will automatically place a market order to close the position. Trailing stop orders can automatically adjust based on the customer's set amount/percentage when the market price changes in the customer's favor, limiting the maximum possible loss while not limiting the potential profit. However, trailing stop orders cannot guarantee a specific execution price and may have an execution price far from the stop loss trigger price.
Additional OrderRefers to an order that can achieve a stop profit or stop loss effect on the main order through attached sub-orders. The types of sub-orders that can be attached include limit orders (used for profit-taking), stop-limit orders/stop-loss orders (used for stop-loss).
Algorithmic Order-TWAPTime-Weighted Average Price algorithm is a simple traditional algorithmic trading strategy. The purpose of the TWAP model is to reduce the market impact of trading while providing a lower average execution price, thereby reducing trading costs. In situations where intraday trading volume cannot be accurately estimated, the model can achieve the basic goal of algorithmic trading well.
Algorithmic Order-VWAPVolume-Weighted Average Price. VWAP strategy is a splitting of large orders into smaller ones that are executed in batches within a specified time period, with the aim of achieving an algorithmic trading strategy that makes the final buy or sell execution price as close as possible to the average market price during that time period.
