EMA Trend

17 thg 2, 2021

The purpose of this script is to identify price trends based on EMAs. The relative position of price to specific EMAs and the position of certain EMAs towards each other are used to determine the trend direction. The script is intended for investors as a tool to define a basis for further evaluation. I do not use the script as a signal generator and would not recommend doing so without the help of additional indicators.

How to work with the script

The major (or long term) trend direction is determined by the 144 EMA much in the same way as the 200 MA is used in other systems. If the price is above the 144 EMA we are in a long term uptrend, below we are in a long term downtrend. This is to be taken with a grain of salt though. The 144 EMA is considerably shorter than the 200 SMA and is more prone to the price fluctuating around it during periods without a strong long term trend. I recommend using this as a confirmation for the short term trend.

The short term trend is derived from the position and slope of the price, the 21 EMA and the 55 EMA. If the price is above the 21 EMA, the 21 above the 55 EMA, both EMAs are sloping upwards and the distance between the two is increasing, we are talking about an uptrend (and vice versa for a downtrend). This is visualized by the color of the fill between the 144 EMA and close price. Green for uptrend, red for downtrend and no color for an undetermined trend.

The EMAs used are: 21, 34, 55, 89, 144, 233. Most of the EMAs are at 50 transparency to appear less dominant. For orientation, the 144 EMA is bright green to indicate its general importance for the trend determination, and the 55 EMAs is not transparent mainly to be able to identify positioning when the EMAs are close together.

Base time frame EMA

The 144 EMA is plotted twice where one is fixed to the daily time frame (can be configured) to be able to have the 144 on different timeframes during analysis. I find this very useful to keep the focus on my main time frame while analyzing trend on lower or higher time frames. This can also be turned off.


Configurability
This script is less configurable than I generally like with my other scripts. The reason is that the title attribute of the plots is not dynamic, and I use the data window often to get exact values from the script to determine buy targets for pullbacks and other things. Hence, I prefer not to have random names (or no names) in there to save mental capacity. If this ever becomes available, I'll gladly add this to this script. Till then, I encourage you to take the script and adjust it to your own needs. It should be simple enough even if you are just starting out in pine.
