In TradingView we can configure several strategy settings with code, including when and how often the script calculates. What are the benefits and drawbacks of calculating with every real-time price update, and how do we enable or disable this feature programmatically? The strategy function programmatically configures a TradingView strategy TradingView, n.
We need to add this function to every strategy script Pine Is tradingview real time Language Tutorialn. When this argument is set to truethe strategy calculates itself with every real-time tick TradingView, n. The advantage of calculating with every tick is a greater is tradingview real time. This advantage does have several important consequences, but for backtesting and order generation:. Configuring TradingView strategy settings programmatically is convenient since then our strategy is added to the chart with the correct, predefined settings.
But manually changing a setting gives more flexibility since multiple instances of the same strategy can use different settings. This opens a window with the different strategy settings. The example strategy below generates a long signal whenever two consecutive price bars close higher and a short signal generates when two bars in a row close lower.
The image is tradingview real time gives an idea of how the finished script. After configuring the strategy, we add two input options:. The input function adds input options to a script. We make this input by setting the type argument of the input function to source Pine Script Language Tutorialn. We set its type argument to integer to create a numerical integer input that accepts whole numbers only Pine Script Language Tutorialn. The ema function calculates an Exponential Moving Average with two arguments: We store the value returned by ema in the emaValue variable for use later on.
Otherwise, when one or both expressions are falsethen the combined result is false too Pine Script Language Tutorialn. Combining these two expressions means that the timeFilter variable holds true whenever the bar happens in April or later. Instead, its purpose is to artificially is tradingview real time the number of orders the strategy generates. So by having the strategy only take trades that happen in April or later, we limit the number of trades that the script makes and prevent that error from happening.
Note that you need to change this timeFilter variable depending on which time frame you use and when you test the above example. Their values are set with 4 expressions that we combine with the and logical operator. That way each expression needs to be true before the variable is assigned true also. And when is tradingview real time or more expressions are falsethen the variable is given a value of false too Pine Script Language Tutorialn.
This is our up trend filter. The other two expressions check recent price action. When all four of these expressions evaluate to truethe enterShort variable is assigned true too. The plot function displays the values of its series argument on the chart, and is tradingview real time them with a continuous line by default TradingView, n. Here we set the series argument to the emaValue variable.
To do this, we first create the backgroundColour variable and assign it a conditional colour with two conditional ternary operators?: A conditional operator works on three values: Now when this variable is truethe first conditional operator returns the green basic TradingView colour. We then store that returned colour in the backgroundColour variable for use later on in the script.
But when that first condition is false, TradingView processes the second conditional operator. That operator evaluates enterShort. Now when the condition of the second conditional operator is also falsethen this operator returns na.
But when we set the colour back to a basic colour or hexadecimal colourthen the plot reappears. That function colours the background of price bars with a specific colour TradingView, n. We set its color argument to the backgroundColour variable to either get a green, red, or invisible na background colour. That argument accepts values that range from 0 no transparency to for full transparency TradingView, n. With id we specify the order identifier TradingView, n.
The long argument, when set to truemakes strategy. In the first strategy. With the long argument set to false is tradingview real time function creates an enter short order. When that order submits is specified with the enterShort variable, which holds true whenever the bar close is tradingview real time the bar EMA and there are two lower closes in a row.
Our example strategy has the following input is tradingview real time. This screenshot was taken immediately is tradingview real time the strategy was is tradingview real time to the chart, and so all bars except the last bar are historical bars.
This can be confusing: After a while the strategy generates a is tradingview real time signal and fills several short orders during the price bar. This time, when the price bar closes, the short signal is still valid:.
Then an enter long order is triggered when the is tradingview real time is already short. For instance, on this real-time bar with a red background a short signal generates:. Then after 10 seconds, we see is tradingview real time visual confirmation that several orders were filled on this bar:.
For this we remove the script from the chart and then re-add it. That causes the strategy to reprocess all price bars except the last bar as historical bars, and this way it treats the bars on which it just performed real-time calculations as historical bars. On this chart we see how the strategy performs on those same bars, but now with just only one calculation per price bar:. For more on this, see TradingView tip: When this optional argument is set to truethe strategy calculates on every real-time tick.
Those additional calculations only happen on real-time data though; on historical data, the strategy still calculates once per bar, on bar close.
When we have a strategy calculate with every real-time price update, it responds quicker to price action. This way the script can open positions sooner, but can also reduce risks quicker.
