  • Open-source API for C/C++, Java, Perl, Python and 100% Managed .NET

Free Open-Source Library

TA-Lib is available under a BSD License allowing it to be integrated in your own open-source or commercial application. (more info)

Why do we need a DLL to get indicator's data ?

The DLL holds all of the calculations. The calculations are computed using TA-LIBs calculations. The custom indicators call the function or calculation for the indicator in the DLL. Without the DLL, you don't have the calculations to compute the indicator.

You could code all of these indicators up as separate custom indicators, doing the math for each one from scratch or from researching them. That would be hard for indicators like the triple exponential moving average or the Hilbert Transform trend line. So this saves you a lot of time. TA-Lib has a community of developers who have checked the calculations for accuracy. So why reinvent the wheel? Also, you have the same indicator calculations across platforms; Excel, MATLAB, Dukascopy's platform, TRAIDE, Quantopian, and a DLL for NinjaTrader and any other platform that uses TA-Lib or has a TA-Lib plugin. So the goal is to have a standardized indicator library across platforms.

There is a ton of documentation on TA-LIB. You can dive into the calculations and create your own features from this DLL in MT4.

Where are you seeing the traide-ma.mqh missing file error?? I've attached an example EA that calls the PRICE_MINUS_TRIMA, PPO, ROC and CCI.

More indicators to come. The 200 above includes all of the indicators in TA-Lib, with each version of the library, we'll add more and more indicators. Chart patterns will be next.

when i compile the bolinger band files, stochastic files, macd ,PPO,APO.

can't open "C:\Users\Computer\AppData\Roaming\MetaQuotes\Terminal\71808ACDDF4589A555C107AF1E5AEBA0\MQL4\include\TRAIDE-Include\traide-ma.mqh" include file

Thank you! I attached to the traide-ma.mqh to fix the following indicators:

BBANDS
MAC2
PRICE_MINUS_BBANDS
STOCH_SLOWK_MINUS_SLOWD
STOCH
STOCHRSI_FASTK_MINUS_FASTD
STOCHRSI
STOCHF_FASTK_MINUS_FASTD
STOCHF
MACD
APO

PPO

In the MT4 terminal go to File --> Open Data Folder, navigate to MQL4 --> Include, right click to create a folder and name it TRAIDE-Include. Copy and paste the attached traide-ma.mqh into the new folder.

This is great! Thanks a lot innovance..

So the chart pattern indicators are still missing? 

You should probably have posted this over on the mql5 site as an article:

https://www.mql5.com/en/articles/mt4/indicators

It seems that this site here is sort of being phased out...
