Time-Weighted Average Price (TWAP)
Tue, Apr 15Time-Weighted Average Price (TWAP) is a trading algorithm that utilizes the weighted average price to execute larger orders while minimizing their impact on market prices. If the orders are not adjusted in a specific manner, it may be relatively easy to predict the trading pattern of the strategy, so parameters can be modified to make the strategy less traceable. Common methods include randomizing the size of orders and/or the delay between them. Additionally, it is possible to set limits on the quantity to ensure it does not exceed a specified percentage of the volume, thereby reducing the strategy's market impact.
TWAP is one of the earliest execution algorithms and is simpler in its calculations compared to Volume Weighted Average Price (VWAP). Unlike many algorithmic trading strategies, TWAP is a passive execution algorithm that waits for the right market price to emerge rather than pursuing it aggressively.
The primary application of TWAP is to distribute large orders throughout the trading day. For instance, if you wish to purchase 100,000 shares of Apple, placing a single large order could significantly affect the market, likely driving the price up. To avoid this, you can specify a time frame over which to buy the shares. The TWAP algorithm will divide the large order into smaller portions and execute them over the designated time period.
While TWAP can serve as an alternative to VWAP, its simplicity comes with certain drawbacks. Even when breaking down large orders, executing them evenly can still lead to trading during periods of low liquidity, which may impact the market. Therefore, it is advisable to use TWAP over shorter time frames or for assets that lack a substantial volume profile.
Trading in a predictable manner can make your strategy vulnerable to detection by other traders or predatory algorithms. To introduce randomness, you can focus on percentage completion over time instead of fixed quantities. For example, in a 1-hour TWAP run, rather than dividing the order into equal parts, you can aim for specific percentage milestones: 25% completion in the first 15 minutes, 50% by the second 15 minutes, and 75% by the third. This approach allows for greater flexibility in order sizes and makes your trading activity appear more random and less predictable.
Although VWAP is more complex due to its inclusion of volume in calculations, TWAP and VWAP values can be similar for instruments with low turnover. However, as market volatility increases, the two indicators tend to diverge. The table below illustrates TWAP and VWAP calculated for the entire trading day. At the beginning of the trading day, the difference is less than a cent, but by the end of the day, the difference has increased to 2 cents. This discrepancy occurs because smaller volume trades at lower prices during the day affect TWAP but not VWAP.

Tariff
A tariff is a tax levied by a government on goods and services brought in from other nations. Tariffs have several functions, such as generating government revenue, shielding domestic industries from foreign competition, and shaping trade policies. In addition to being a revenue source for the government, tariffs can regulate foreign trade and impose taxes on foreign products to promote or protect domestic industries. Tariffs are among the most commonly used tools of protectionism, alongside import quotas, export quotas, and other non-tariff trade barriers. The term "tariff" comes from the French word tarif, meaning 'set price', which is derived from the Italian tariffa, meaning 'mandated price; schedule of taxes and customs'. Ultimately, this term traces back to the Arabic word taʿrīf, meaning 'notification'.
