Hi lec0456,

Unfortunately we cannot provide source code for built in indicators.

Panagiotis,

I am not sure why this is the policy at Spotware. For Indicators that are not proprietary, the code should be open-source. Verifying the calculations are important and customizing them is a benefit for traders.

Spotware used to provide the code for indicators, why has this changed and how does this benefit the business? Spotware gains nothing by hiding the code. Traders who are putting their money on the line should be able to see the calculations there trades are being based on.

Please raise these concerns to management and see if this is the something that can be changed.

Thanks,

Louis

Hi lec0456,

The calculation of some indicators might be public domain knowledge but the source code for each indicator implementation is proprietary work of Spotware. If you wish to verify the results of an indicator, there are many ways to do so without having access to the source code.
