Pec sdk

Hi! If it is any, what is the best alternative to this product for private use?
Thanks!

Best alternative will be either Java API or Order2Go API (can use C++, C#, VB, and more).

Both of these apis will give you historic and live data. You can also trade using these APIs. Most of all, they are both free.

We are using PEC SDK C++ version and developed a Windows C++ server to connect to your servers. However, we want to migrate to Linux, what API can I use?

Depending on how you used PEC, you may want to look into the Java API or FX Connect in order to access streaming rates on a Linux box.
