Best Auto Trendline Indicator – Indicators for MT4, MT5 and NinjaTrader

In trading, technical analysis plays an important part. It is used to evaluate and predict the future price movement of a market  by interpreting the patterns, trends, and volume that can be seen in a chart. 

A trendline indicator is a simple yet very effective technical indicator in trading.

 Traders use trendlines to assess an asset or security behavior and make profitable trading decisions. 

They also look at the data behind a past trend behavior of a market to identify the factors that contribute to that movement. 

When the historical data has been studied, it will be easier to identify significant movement in the current chart that resembles what has happened before. The same behavior will more likely happen again. 

Trends can be upward, downtrend, and horizontal. An uptrend happens when prices continuously rise and the overall market direction is upwards. It implies a bullish trend. 

downtrend happens when prices fall for a period of time and implies a bearish trend.

 A horizontal trend or sideways trend happens when supply and demand are equal. 

These trends are driven by market sentiment.

Technical indicators such as trend lines are used in a charting platform to visualize the market activity. This makes it easier for traders to find the most profitable trading opportunities. 


MetaTrader is one of the most popular trading platforms due to its powerful features. It is widely offered by trustworthy brokers which is why traders do not have to worry about this software. 

MetaTrader 4 or MT4 is the first version of the MetaTrader platform which is designed for Forex and futures markets. What traders love about it is that it can be used by anyone regardless of skill level. Automated trading is also available in MT4, allowing traders to place trades faster and easier. 

But what traders most likely like about MT4 is its technical analysis capability. It has 30 built-in indicators and 24 graphical objects which can be viewed in 9 timeframes. 

Using these tools gives a detailed view of the price dynamics which helps traders analyze the market better and find the best entry and exit points of a trade. 

MT4 also has its own programming language called MQL4 which lets traders create their own trading indicators and trading robots. Alternatively, you may access the MetaTrader Market in the MT4 or MT5 platform to browse and purchase indicators or trading robots to your liking. 

MT4 MetaTrader Trend Lines Indicators

Indicators in MT4 are classified into two categories: Trend and oscillators. Below are the best trend line indicators that you can use in the platform:

  • Average Directional Index (ADX)
  • Alligator Indicator
  • Zig Zag Indicator
  • Moving Average Convergence Divergence (MACD)
  • Bollinger Bands
  • Moving Average Indicator
  • Parabolic Stop and Reverse Indicator
  • Envelopes Indicator
  • Standard Deviation
  • Ichimoku Kinko Hyo

These are only some of the most popular trendline indicators that you can use in MT4, but you may also download custom indicators that will fit with your strategy. 

You may also combine these with other indicators to enhance your chart analysis. 


MetaTrader 5 or MT5 is the newest version of the MetaTrader trading platform. It is designed to trade in the Forex, futures, and stock markets.

 It has an upgraded technical analysis capability with the addition of Depth of Market which allows traders to view the volume behind a market.

 There are already 38 built-in technical indicators and 44 analytical objects which can all be viewed in 21 timeframes. Traders also have two additional order types, Buy Stop Limit and Sell Stop Limit. 

MT5 uses a new programming language called MQL5. Nothing much has changed from MQL4 but indicators and other tools from MQL4 should be converted to MQL5 if the trader wants to use MT5. 

However, coding is much easier to do in MT5 so anyone can create their indicators with little difficulty. 

MT5 MetaTrader Technical Indicators

Most of the trendline indicators in MT4 can already be found in MT5 such as ADX, Bollinger Bands, Moving Average, and Parabolic SAR. However, there are also additional trend indicators that can be used by MT5 users:

  • ADX Wilder
  • Double Exponential Moving Average

A trendline indicator is important in technical analysis which is why you should know how to derive information from it. 

It highlights and confirms existing trends or price ranges. Trendlines connect two price points in a chart and shows whether there is an uptrend or downtrend. 

If the trendline indicator has drawn the lines in the chart, you may now use it to complement your trading strategy. Since a trendline defines support and resistance levels, you can identify whether there is going to be a possible breakout or reversal. A breakout is when an asset’s price breaks through a level while a reversal is when an asset’s price bounces from a level. 

When it comes to a breakout, identify a bearish trend, wait for a trendline breakout, and then buy. The same goes for the opposite. It is time to sell when a breakout happens in a bullish trend. 

In reversal trading strategy, when a trendline bounce occurs in a bearish trend, it depicts a sell signal. The opposite happens when a trendline bounce occurs in a bullish trend.
