is the syntax of single-line functions: After the function f has been declared, itâs possible to call it using different types of arguments: The type of the value returned by function f is determined automatically Here we can see that the trailing stop (in red) jumps up at each swing until it is taken out.
Asking for help, clarification, or responding to other answers. can be used to create scripts. The easiest way is to think of it in these terms, your_indicator = valuewhen(another_condition, value_to_display, occurrence) The indicator's last line of code then executes the bgcolor() function to apply that colour to the chart. Without that, the nested if statement never executes. This will plot the value when the condition was true on the n-th most recent occurrence. So they run when the strategy has an open position (strategy.position_size != 0). Those values display as a regular line plot. V4 pine is clearly affecting the math calculation via bad syntax. There are two possible paths through this code. There we have a line of code that always runs when that condition is true. But here's the thing. It presents a chicken and an egg scenario that can often be tricky to figure out. Or maybe just publish the script on tradingview and add here a link to the published script. and depends on the type of the arguments used in each particular function call. sad, anxious, confused, frustrated. of the functionâs body. We store that exit level in the priceTarget variable. Local scopes cannot intersect with each other. yep man you worked it out. I want to plot a line of that highest point. Scopes in the script ¶ Variables declared outside the body of a function or of other local blocks belong to the global scope. Then we calculate an Exponential Moving Average (EMA) with the ema() function. :), Struggling with v2 to v4 pinescript Conversion, “Cannot modify global variable inside function” Error, Podcast 283: Cleaning up the cloud to help fight climate change, How to lead with clarity and empathy in the remote world, Creating new Help Center documents for Review queues: Project overview, Review queue Help Center draft: Triage queue, TradingView Cannot use mutable variable as an argument for security function, Using PineScript to reassess variable value on each candle to prevent repainting errors.

Let's say we have the following nested if statement: Here we got an if/else statement with nested if statement. variables also belong to the global scope.
When those two things are the case, we close the ‘EL’ order with the strategy.close() function. In the example code, the condition given to valuewhen() checks whether the position size has increased. If we don't use multiples of 4 spaces (or 1 tab), then TradingView cannot interpret our code. A type of compartment that rises out of a desk.
type of variable a is series because the arguments are both series. So we don't take buy and sell signals on Friday. The entry criteria are not important to understanding the concept and can safely be ignored or replaced with your own criteria. If this post saved you time and effort, please consider support the site!
However, at the same time we can only calculate whether to close condition after calculating the entry_rsiline! There's no code between the first and second if test. Start by typing a product or service name and we will look it up! If these have not been declared, then we will receive an error. See my TradingView programming services, Have a programming question?
There are many ways to support us and some won’t even cost you a penny. When it is, the code indented below if runs.
The last part of the strategy's code handles open trades. Why would a compass not work in my world? I sense that he may not be the only one who has faced this challenge. See functions we can execute in if statements for more. Could anyone have any idea that achive a constant value series with the last bar value ? Instead, the second if condition simply evaluates an additional condition. be the result of the functionâs call. There are two ways we can approach this.
Pine Scipt functions do not support recursion. To help visualize this, we will plot the saved RSI value. —–. indentation (4 spaces or 1 tab). (When there's no cross, this if statement implicitly returns the na value.). When that tests true, a nested if statement runs. When true, the code under the first if run and TradingView is done with this if/else statement.
