#High volume but no price movement code
When our code checks if the current bar’s high or low equals the highest high or lowest low, we cannot be sure that the bar reached a new extreme price or that it merely equals the previous highest high or lowest low.
Note that this also includes a subtle issue. That is, high = highest(high, 20) will be true when prices reach a new 20-bar high. If our code monitors for new highs or lows, we should check whether the current bar equals ( =) the highest high or lowest low. That can make new highs and lows harder to spot on the chart. That’s because breakouts cannot happen: the best a bar can do is equal the highest high or lowest low, but not cross it. It can be a disadvantage to calculate the extreme prices this way. This way of computing the highest high and lowest low has these features: This makes sense because we calculated those extreme values by including data from the bar that the script calculates on. Here’s how those extreme highs and lows look on the chart:Īs we can see, no bar ever crosses the highest high or lowest low. The highest high and lowest low that we calculate here, however, include data from the bar that the script calculates on. And the lowest() function runs on low prices for the same number of bars. Here we have highest() run on high prices for 20 bars. So to fetch the 15-bar highest high we simply do: That makes the function’s data default to high prices from the chart’s instrument. The first approach is to only specify the number of bars. We can execute the highest() function in two ways. And the second is the number of bars to calculate on (TradingView, n.d.). The first is the data to retrieve the highest value from. To fetch a highest value (like the highest high) we use highest(). # Retrieve the highest value in TradingView with highest() Let’s take a closer look at how we can use both functions. But we can use highest() to get the highest RSI value from the last 10 real-time ticks. So we can use highest() to get the 10-bar highest high. That means those functions cannot perform their calculation inside a price bar. #High volume but no price movement series
Since those series are tied to bars, with one value for each bar, the highest() and lowest() functions always calculate the biggest and smallest value over a certain number of bars.
In TradingView most values are a series, and those series have the same length as the number of bars on the chart (TradingView Wiki, 2017a). The highest() and lowest() functions work on a series of values.
And the lowest() function returns the lowest value for the specified data and number of bars. The highest() function returns the highest value for the specified data and number of bars. Here’s how we fetch the highest high and lowest low in TradingView: We can also use them with volume values or oscillators to see when prices reach a relative high or low. We use them to monitor for highest high and lowest low breakouts, like most trend-following strategies do. The largest and smallest extreme values are pretty common in TradingView Pine script. # Get extreme high and low prices in TradingView Pine Example indicator: plot the highest high and lowest low.
