here you can find some indicators that i use to simplify my trading

You will find 3 files for each indicator
cs file is the source code

If you are not a developer and want to use the indicator you can download the dll and pdb extension files

Copy them on a new folder inside your Quantower strategy location, example, mine is:
*C:\Users\Alejandro\Downloads\AMP Quantower\Settings\Scripts\Indicators*

inside Indicators folder create a new one, example, for "Order Flow Tools" i will create a folder called the same "Order Flow Tools", now we have the next folder location:
*C:\Users\Alejandro\Downloads\AMP Quantower\Settings\Scripts\Indicators\Order Flow Tools*

Here copy the dll and pdb files

Restart QuanTower if it does not detect the files automatically
