Solve Your plotshape Function Error in TradingView Pine Script

If you're working with TradingView's Pine Script to analyze trading strategies, you may run into a frustrating issue when trying to plot buy and sell signals using the plotshape function. One common mistake that can result in errors is related to the arguments passed into this function. In this guide, we'll address a common error you might encounter and guide you through the solution.

The Problem

The main challenge arises when you receive an error message that indicates you're passing the wrong type of argument to the plotshape function:

This error is particularly vexing as it interrupts your workflow and prevents you from displaying your desired buy and sell signals on the chart.

Identifying the Error

The culprit behind this specific error is the use of a boolean value for the transp argument within your plotshape call. According to Pine Script's documentation, the transp parameter must be an integer ranging from 0 to 100, where:

0 means fully opaque

100 means fully transparent

When you inadvertently set transp to a boolean value (true or false), the compiler throws an error, as it is expecting an integer.

The Solution

To fix the error, it's critical to ensure that the arguments passed to the plotshape function are of the correct types. Here’s a modified version of the initial code that fixes the issue while also ensuring the functionality to plot your signals accurately:

Key Changes Made:

Transp Argument: Updated the transp parameter in both plotshape functions to a numeric value (like 80), which is suitable for indicating the transparency level.

Syntax Corrections: Additionally, made minor corrections to ensure the logical conditions are accurately represented.

Conclusion

By simply ensuring that the transparency argument in your plotshape function calls are integers, you can overcome the pesky error that halts your progress. This small adjustment allows you to visualize your trading signals effectively, making your Pine Script coding experience much smoother.
