vwap trading algorithm: Volume Weighted Average Price VWAP Algorithm

technical analysis

Prices are dynamic and what appears to be a good price at one point in the day may not be by day’s end. If a trader wanted a 10-period MVWAP, they would simply wait for the first 10 periods to elapse, then average the first 10 VWAP calculations. This would provide the trader with the MVWAP that starts being plotted at period 10.

As an example, suppose a trader sends a VWAP order with a 2% volume limit on an order that turns out to be 10% of volume. In this case, the algorithm will track the market volume more closely than the volume schedule, because the volume constraint is likely to be binding for most, if not all, of the order life. The more restrictive the volume limit, the more a VWAP order will resemble a POV order, with all the potential for adverse consequences as well. It can be anchored at the start of the day, week, month, quarter or year.

Reason # 7: VWAP Can Help Beat High-Frequency Algorithms

By using the latest values from the dataframe, we create boolean values for buy and sell signals. The trend of the VWAP shows if buyers or sellers are in control at a particular moment. If the VWAP is rising, then buyers are in control and vice versa.

Day traders often develop a trading strategy to analyze the intraday price movement relative to the VWAP support and resistance. If prices go through VWAP, traders usually wait to confirm the broken trend and wait for another touch from the other side. VWAP is a modified version of the moving average known from technical analysis.

This mean-reversion strategy assumes that a stock’s share price will generally tend to come back to its VWAP over time. When a stock’s share price gets too far above its VWAP, mean-reversion traders sell. This is because seasoned traders are selling their long positions into strength. On the flip side, novice day traders are trying to buy these breakouts. This gives the seasoned traders the liquidity to unload their shares to the unsuspecting public. Remember, day traders have only minutes to a few hours for a trade to work out.

In directional markets where momentum has signalled a breakout trading pattern, VWAP can be used as a support or resistance line. In sideways trading markets and the absence of a breakout, price can be expected to trade either side of VWAP and revert to it as a mean average of that day’s trading. In this scenario, the institutional investors can be expected to be buying when price is below the VWAP and selling when it is above. The balance provided by sellers and buyers matching each other in relatively equal measure creates trading opportunities caused by the churning nature of price movement. The volume weighted average price is more than just modifying a classic moving average.


If that is the case, it could indicate a big institutional investor building into a position. Such activity can carry on through the day, meaning the buying or selling activity of that ‘real’ money could be something to tag along with. If momentum fizzles out, then it could be a day to trade a different market where there is some momentum or alternatively try to scalp price moves in a sideways market. Take, for example, a hedge fund that wants to sell out of a stock where it has a position that is a substantial percentage of the total market cap of the firm.

The Significance of Anchored VWAP

Volume constraints are widely used as a tool to prevent an algorithm from having excessive market impact. Volume constraints allow the trader to specify the maximum fraction of volume the algorithm can reach at any point in the execution. In the case of a 5% volume limit on a 1,000-contract order, the algorithm would only complete the order if at least 20,000 contracts are being traded in the market. If market volume is only 12,000 contracts, the algorithm could only trade 600 at most, with the remaining 400 shares left unexecuted at the end time.

9 the first component of the selection cost, which measures the price deviation from VWAP in each volume-time bucket. In practice, this component is fairly stable throughout time and proportional to the spread of the security. The two second SD of today’s VWAP are resistance and support levels. However, for our better understanding let us look at the calculation.

There are many moving average types to choose from, and which one you should go for depends not only on your trading style but also on the characteristics of the strategy you trade. Average price is the mean price of an asset or security observed over some period of time. When a security is trending, we can use VWAP and MVWAP to gain information from the market. If the price is above VWAP, it is a good intraday price to sell. If the price is below VWAP, it is a good intraday price to buy.

Traders mainly use three aspects of the VWAP for opening and managing positions

This will allow you vwap trading algorithm to analyze the price action before you add to the trade. As you monitor your trade entry, you can “size up” as the stock find its footing near VWAP. There are times when the price action of the stock shows no sign of weakness. As buyers continue to buy, buy, buy, and short sellers continue to cover, the price pushes higher. VWAP is a moving indicator used intraday – starting with the first bar and ending with the last of the day. Anchored vwap, on the other hand, is tethered to a specific bar and displays the cumulative struggle of bulls and bears from that bar.

Ironically, it is most often made by cost-sensitive traders with relatively small alphas that they are trying to preserve by controlling execution costs via tight volume constraints. In such a scenario, this cost-sensitive trader’s desire to limit costs may actually increase their costs. With the exception of strong trading days, the market price will not stay above the outer deviation level for a long time. With institutional algorithms executing the majority of trading volume, VWAP is something traders should watch. I use VWAP in conjunction with many of my short strategies, including the aforementioned parabolic short. Understanding VWAP is a valuable addition to any algorithmic trader’s repertoire.

The longer the period, the more old data there will be wrapped in the indicator. We want to minimize this in order to catch reversals as early as possible, so we want to shorten the period. Big institutional investors buy and sell large amounts of stock in a variety of ways (through different brokers, using different procedures, tempos, etc.). They are interested in judging the ex-post “quality of execution” , i.e. how good a price they are getting when buying and selling. Even being consistently off by a few pennies could be very costly in the long run…

  • They might accelerate the pace of buying if the current price is below VWAP for example, and vice versa.
  • To get a reliable estimate of the price at which a security was traded for a given period, we take the average of the price data, in this case, the average of the high, low, and close price.
  • Even though it is primarily used on an intraday basis, there can still be a great deal of lag between the indicator and price.
  • With such a good average price, you can make the decision to kill the trade if need be.
  • We make the class Serializable so that it can be sent across remoting channels.

This https://1investing.in/ below depicts a 5-minute time frame during a period of just over two-days duration . The VWAP line shown here makes for an excellent intraday strategy filter. Not all days trade like this, but these two days represented a fairly sideways price action, and under such conditions, intraday traders like to have a game plan. A strategy to make trades based on a reversion to the average price for the day would work well here. Many traders pay attention to this level because it’s a good support and resistance level. The most common algorithmic trading strategies follow trends in moving averages, channel breakouts, price level movements, and related technical indicators.

This presented a nice buying opportunity, as the market indeed did move up shortly thereafter. You take every value for every bar in the current trading day you got from the previous step, and add them cumulatively. To get the final WVAP value, you divide this value by the cumulative volume. You first have to calculate the typical price for the current bar. This is the sum of the low, close, and high, divided by three. This is a significant difference to regular moving averages, and means that the formula weighs each datapoint differently depending on the volume with which the bar was formed.


Index funds also use VWAP to track an index as they are particularly sensitive to impacting the index they are tracking. A day of bullish momentum would be defined as one with price trading above VWAP and a bearish one a day when price trades below it. VWAP can be used to gain an understanding of the market as much as it can be used to identify trade entry and exit points. It ties calculations to a specific price bar decided by the trader. It is similar to the traditional VWAP, as it incorporates price and trading volume in a weighted average. Like VWAP, it can also identify the areas of support and resistance on the chart.
