Pine Script Tutorial How To Develop Real Trading Strategies On TradingView

Line 6 calls the plot() function to plot the closing price of the default security. Line 1 contains a comment that explains the licensing agreement for using the code. The second line also includes a comment containing the author name of the code, which by default is your username. The Pine Script compiler ignores the comments on lines 1 and 2.

Can you use Python in TradingView?

The inputs allow for easy customization of Bollinger band parameters and allow this indicator to work with any time frame combination. This is based on a scalping strategy that what is terminal value I used when I first started trading. It is a mean reversion strategy that works well during the early Asian session in the Forex markets when things are generally quiet.

Pine Editor

Note that the defval value we use is a call to thetimestamp()function. Pine studies, as the one in the previous example, also containcalculations, but cannot be used in backtesting. Because they do notmake use of the broker emulator, they use less resources and will runfaster. This regularly updated module will again prove helpful to the non-coders trying to develop their own scripts. This premium PineScript programming course has 5+ hours of video materials with 50+ code examples to get you on track with TradingView.

Technical Analysis with Indicators

We then define two moving averages, the fast-moving average (fast_ma) and the slow-moving average (slow_ma), using the ta.sma() function. The plot() function then plots the fast and slow-moving averages on the chart. You need to pass the Quandl data ID, the bars’ gap value, https://www.1investing.in/ and the data column’s index value. For instance, the following script displays plots containing values from the first row’s four columns. The barmerge.gaps_off means no gaps are displayed between bars. And with that, we have covered the Pine Script language fundamentals.

They are only there for conveying information to the code reader. Line 4 contains an annotation comment telling the compiler about the Pine Script version for code compilation. If you do not specify the version, the Pine Script compiler will use version 1.0. Unlike simple comments, annotation comments convey information to compilers.

There is a wealth of information here and I used this resource as reference material for a number of lessons on this website (and in my own scripts). Either way, the most productive way to learn is always to start playing with real code early. Make slight changes to the code and see what impact they have, and you’ll be on your way. You can write two lines of Pine to do what could take hundreds in other languages. This document aims to provide information that will be useful for newcomers to the Pine Script programming language. Pine Script is the programming language used on the TradingView charting platform.

The first thing we will do is store Google’s daily open and closing price into a variable. The rest of the script remains unchanged from the prior example. The ATR indicator calculates the average movement over the last number of specified bars. In our last example, the trade execution was determined by moving average crossovers and crossunders.

1. We designed Pine Script™ as a lightweight, yet powerful, languagefor developing indicators and strategies that you can then backtest.
2. Theinput.enum()function creates a dropdown input that displays field titlescorresponding to distinct members (possible values) of anenum type.
3. A strategy in Pine Script is a set of programmed rules that automate trading decisions based on technical indicators and price patterns.
4. One of the main advantages of Pine Script is its flexibility.
5. A well-written indicator often looks like pure gibberish to the untrained eye.
6. In the following example, we store the boolean input from a user in the bool_input variable.

The primary purpose of indicators is to provide technical analysis of various securities. In this section, we will go into more detail about Pine Script indicators. In production environments, you would allow users to provide input values. Likewise, to receive multiple values from a function,  pass receiving variables inside square brackets and separate them by commas.

The following window will open where you can see some default code. This is your Pine Editor, where you will write all your Pine Script code. To do so, sign up with a TradingView account, open a chart of your favorite security, and write Pine Script code in the Pine Editor.

The first attribute to the function is the security ticker ID, the second is the time frame, and the third is the indicator you want to retrieve. The following script calculates a simple moving average of length three using the history-referencing operator. Like most other programming languages, Pine Script has the following operators.

We’ve seen that the security function can be used to display data for stocks not shown on the screen. Our exits are working and being plotted on our main chart along with the long and short entries. If we save and add to chart, the strategy will run and automatically open the Strategy Tester window which will display some important stats. Let’s go through an example where we grab the price of Apple even though we don’t have its chart open. In the image above, this is the line chart that is drawn in blue.

The following script sets the line width of the close plot to 3. The format attribute is another important attribute that sets the format of your plot. For instance, Pine Script displays volume values in all digits. If you set the format attribute to format.volume, you will see volume values in K (for thousands) and M (for millions). To create an indicator, we use the indicator() function, which tells the Pine Script compiler to import all indicator-related namespaces.

I would recommend starting with the Python tutorial because Python is a popular programming language for traders and trading systems (and is very similar to Pine Script in its style). If I wanted to execute the strategy discussed above I wouldn’t actually want all my funds on an exchange account buying and selling spot BTC. I would probably flip the strategy so that it opened a short position on a perpetual futures trading contract whenever the price fell below the 200hr moving average and other filters were met. The findings in this section reveal that complexity doesn’t necessarily guarantee superior performance over a simpler strategy. While a complex approach might mitigate risk, it could yield lower overall profits than a riskier strategy. Ultimately, the pursuit of the optimal strategy lies beyond the scope of this article.
