Downloaded the hzexchange zip and extracted it to see if I could make it work.
Here is your problem from ...\Desktop\hzxchange.net-1.01\README.md:

Needs a solution for HZ/BTC price (same origin policy, didn't find an api with CORS header yet)
It's quite easy to understand that until Poloniex stops forwarding our former "delisted" HZ website link to its old HZ/BTC pair (later forwarded the link below to ETH/BTC pair, now its a BTC/USDT pair - you all know what I mean):
EDIT: forgot to link y'all
https://poloniex.com/exchange#btc_hzEDIT2: now that I have clicked the link from bitcointalk.org I am being forwarded to (
https://poloniex.com/exchange/USDT_STR) STR/USDT
---back to original post---
Go ahead and click it. If you're wondering where CORs is used it is in setting up the platform and changing the nhzdefault.properties file and set the "false" to "true" - my server/node uses Java (Horizon NRS from C:\...) and I can open up an app I created for Internet Explorer to run my wallet and access the platform itself locally just fine

Probably why mark never finished migrating to Poloniex and why they have offered similar exchanges since they took part of Horizon stealth-ly away from idiots like me who just used to use web exchanges and not know a thing about the internet, mobile data, the web, the world wide web etc.
But this platform still has many peers - sometimes I get as many as 17! I will run the Horizon Server I setup as a way to support and secure the network as long as it lets me

Why let ETH be the only one locking away coins for DeFi when HZ is the origin of Original Proof-of-Stake as well as running just fine according to rules of Nakamoto Consensus. The more HZ one holds on Horizon, the more virtual hashing power it should have for PoS. =P
