HFT Scalping

#1
Hi,

I came across this site for Co Location Provider and Faster API execution. https://symphonyfintech.com/, Does any one have a experience with provider? How reliable their service and latency?

I need a system who provides API for HFT Scalping which need to execute my strategy. I tried with most of the brokers and order execution is always latent when the higher size orders are placed. I do see the latency for 20 Lots of Bank Nifty. I am worried about the latent when the lots are increased to 50/100.

Any suggestions from forum experts are always welcome. Suggestions are welcome for Co Location as well.
