Pine Script vs MQL4 vs MQL5
Traders using TradingView may prefer Pine Script for its user-friendly interface and extensive charting capabilities. Those using the MT4 platform may opt for MQL4, benefiting from its simplicity and large community support. Traders who want to leverage advanced features, improved performance, and multi-asset trading may choose MQL5 on the MT5 platform. I will explain everything about pine script and will teach you from basics to advance. Basically, I’m an engineer, a full-time forex trader, and have in-depth knowledge of the python programming language.
Data is built-in and the platform is geared toward creating custom indicators and strategies. When the same code is executed on the next bar, the fourth in the dataset,
close will now contain the closing price of that bar, and the same close[1]
used in your code will now refer to the close of the third bar. The close of the first bar in the dataset will now be close[3]
and this time close[4] will return shakepay review na. When the market for the chart’s symbol is open and the script is executing on the chart’s last bar, the realtime bar,
close returns the value of the current price. It will only contain the actual closing price of the realtime bar the last time the script is executed on that bar, when it closes. The close of the first bar in the dataset will now be close[3],
and this time close[4] will return na.
The MQL4 community offers a wealth of shared indicators, libraries, and resources, providing traders with a vast selection of pre-built indicators or inspiration for creating their own. The built-in data from Pine Script can be very advantageous for traders because testing strategies or creating indicators in other languages involves sourcing your own data. It is also incredibly easy to learn as Pine script syntax is readable and simpler than other programming languages.
To access the input options, click on the gear icon next to the name of your strategy in the data window. And lastly, we told Pine script we are interested in the closing price. Note that the data window shows “My Script” in the upper left-hand corner.
If you need help learning how to appropriately and properly apply the backtesting process in your own trading, check out more of my resources on the subject over at backtestingfx.com. Pine Script allows you to objectively define your trading setups and process using computer code so that there is zero question about whether or not you have a valid and profitable trading opportunity. While there are tons more custom indicators on TradingView, the most beneficial would be developed by yourself with Pine Script. You’ll find numerous trading view indicators developed in Pine Script by other users. It’s important to keep your code organized and well-commented.
We can duplicate most of the inputs from the regular Bollinger band indicator (as shown in the image above) for our custom indicator. Another common plotting function is plotshape() which allows you to plot various shapes. This one is quite popular as a lot of people use it to plot arrows on the top or bottom of bars to show buy or sell signals. Most Forex traders are paying attention to the London and New York sessions. Let’s program an indicator that will tell us with a quick glance at the chart when the markets are expected to be the busiest.
- Arrays, in comparison, can have constant or variable sizes, and their content or indexing structure
is not modified by the runtime environment. - In the code above, we calculated the stop loss by taking the low of the bar at the time of entry and subtracting the average true range multiplied by two.
- Like a mechanical machine, it does the same thing over and over again without deviation.
- This is stored in the tf variable created by the earlier user input.
In the next example, we will create a moving average cross-over strategy with a few additional parameters. This will grab the closing price for whichever security you have showing in your main chart window. We will start with our basic declarations and use the security function we created in our last example.
Understanding Pine Script
Whether you’re an experienced coder or new to programming, Pine Script offers a straightforward way to enhance your charting and analysis on TradingView. Pine Script is a powerful tool that empowers traders to create custom indicators and trading strategies directly on the TradingView platform. Its user-friendly syntax and extensive library of functions make it accessible to traders of all skill levels. Indicator creation is a powerful aspect of MQL4, enabling traders to develop unique tools for technical analysis and generate trading signals.

It’s completely free to use, mostly open source, and you don’t need to be a rocket scientist to work with it. One of the key advantages of Pine Script is its active and supportive community. TradingView users can share their Pine Script creations, collaborate with others, and access a wide range of pre-built indicators and strategies. This community aspect fosters learning, knowledge sharing, and the opportunity to leverage the expertise of other traders and developers.
Why should I use Pine script?
The boolean value changes the plot color while the integer value sets the plot value. Likewise, to receive multiple values from a function, pass receiving variables inside square brackets and separate them by commas. You can create single-line or multi-line user-defined functions. https://forex-review.net/ You can encapsulate custom Pine Script functionalities in user-defined functions. If you change the time frame to minutes (30m in the following screenshot), the plot color changes to red. The close, open, volume, etc., are some of the most common Pine Script built-in variables.

If at least one of these operands has a series type, then
the type of the result will also be series (a series of logical
values). If both operands have a numerical type, then the result will be
of the logical type bool. The [] operator is used after a variable, expression or function call. The value used inside the square brackets of the operator is the offset in the past we want to refer to.
I have many years of experience in the forex industry having reviewed thousands of forex robots, brokers, strategies, courses and more. I share my knowledge with you for free to help you learn more about the crazy world of forex trading! A Code basically consists of constants, variables, and functions. We apply specific conditions and whenever the program meets those conditions then it operates. Pine Script contains several built-in variables and functions you can use to perform various tasks. The following script calculates a simple moving average of length 10 using a while loop.

If you have knowledge of the python programming language then it is a plus point for you and you will learn pinescript easily. The history-referencing operator allows you to fetch previous bar values. The history-referencing is used after a variable or function call. Inside square brackets, you have to pass an integer value, which refers to the offset in the past.
Why shouldn’t I use Pine script?
The rest of the script remains unchanged from the prior example. So if the stock moves on average $5 per bar, we are setting our take profit $10 below the low. We will build on this script and set specific stop losses and take profits. We can use the Average True Range (ATR) to calculate the levels for these. So when the crossover or crossunder occurs, these variables will get updated to True which is a Boolean value. Fortunately, TradingView has a built-in function for that already, so we don’t need to code it manually.
