"Algo Trading"- Windows Based VPS-Good & Cheap both- Suggestions

#2
Both appear to be good, but a bit costly. I run my own algo trading platform which is built in .Net in Wishosting. My preferred configuration is 4GB RAM with 2 core CPU. That comes to $7 pm. Check for
KVM HDD Plus which now comes with 8GB ECC RAM and 2 core at $7

Have you looked cloud infrastructure like AWS/GCP/Azure/Digital Ocean. I personally use GCP, I have tried AWS and Digital ocean in the past as well

You can get servers in Mumbai to reduce latency, you can optimise cost by turning it off during off-market hours..

Any particular reason you are specifically looking for VPS
