Components

Sai consists of five parts:

• DMS — historical data maintenance and sync
• PPT — paper trading and webhooks
• stime — simulated time service
• ZuiLow — strategy scheduling and multi-broker execution
• simulate — full-stack simulation (stime + ZuiLow + PPT + DMS)

To Brokers:

• Futu NiuNiu — Disappointing!!! No sub-account, no US market simulation account.
• IBKR — Also disappointing!!! No headless Gateway (terminal-only).

This Project: From Backtest, Simulate to Real trading, it works !!!

UI snapshots

• DMS
  

• PPT
  

• stime / simulate
  

• ZuiLow (accounts, brokers, jobs, live, status)
  
  
  
  
  

Try it on Docker

Prerequisites: Docker and Docker Compose. DMS is optional (external); set DMS_BASE_URL in docker/.env if you use it.

First run (from repo root):

cd simlulate
./deploy_sim.sh up

This builds and starts stime, ZuiLow, and PPT. After startup you'll see:

Service	URL (default)
stime (set/advance time)	http://localhost:11185
ZuiLow	http://localhost:11180
PPT	http://localhost:11182

Run each subproject independently

From the repo root, each component can be started on its own (install deps and set config per project; see each project's README).

Project	Command (in project dir)	Default URL / port
DMS	cd dms && ./start_dms.sh	http://localhost:11183
stime	cd stime && python app.py	http://localhost:11185
PPT	cd ppt && ./start_ppt.sh	http://localhost:11182
ZuiLow	cd zuilow && ./start_zuilow.sh	http://localhost:11180

Alternatively run with python app.py inside each project (after pip install -r requirements.txt and env/config). DMS and PPT may need DMS_BASE_URL / DB config; ZuiLow may need datasource and broker config. The simulate stack (see above) runs stime + ZuiLow + PPT together via Docker.
