Python 3 -m pip install -U zvt
It's good for backtest and research, but it is not applicable for real-time market data and user interaction.
After the installation is complete, enter zvt on the command line
zvtThe example shown here relies on data, factor, trader, please readdocs
The core concept of the system is visual, and the name of the interface corresponds to it one-to-one, so it is also uniform and extensible.
You can write and run the strategy in your favorite ide, and then view its related targets, factor, signal and performance on the UI.
It is more flexible and more scalable, more suitable for handling real-time market data and user interaction. Combined with the dynamic tag system provided by ZVT, it offers a trading approach that combines AI with human intervention.
- Init tag system
run following scripts:
https://github /zvtvz/zvt/blob/master/src/zvt/tasks/init_tag_system.py https://github /zvtvz/zvt/blob/master/src/zvt/tasks/stock_pool_runner.py https://github /zvtvz/zvt/blob/master/src/zvt/tasks/qmt_data_runner.py https://github /zvtvz/zvt/blob/master/src/zvt/tasks/qmt_tick_runner.py
- Install uvicorn
pip install uvicorn- Run zvt server
After the installation is complete, enter zvt_server on the command line
zvt_serverOr run it from source code: https://github /zvtvz/zvt/blob/master/src/zvt/zvt_server.py
- Check the api docs
openhttp://127.0.0.1:8090/docs
- Deploy the front end service
Front end source code:https://github /zvtvz/zvt_ui
Change the env file: https://github /zvtvz/zvt_ui/blob/main/.env
Set {your server IP} to zvt_server IP
NEXT_PUBLIC_SERVER = {your server IP}
Then refer to the frontend's README to start the frontend service.
openhttp://127.0.0.1:3000/trade
>>> from zvt.domain import Stock, Stock1dHfqKdata
>>> from zvt.ml import MaStockMLMachine
>>> Stock.record_data(provider= "em" )
>>> entity_ids = [ "stock_sz_000001", "stock_sz_000338", "stock_sh_601318" ]
>>> Stock1dHfqKdata.record_data(provider= "em", entity_ids=entity_ids, sleeping_time=1)
>>> machine = MaStockMLMachine(entity_ids=[ "stock_sz_000001" ], data_provider= "em" )
>>> machine.train()
>>> machine.predict()
>>> machine.draw_result(entity_id= "stock_sz_000001" )
The few lines of code above has done: data capture, persistence, incremental update, machine learning, prediction, and display results. Once you are familiar with the core concepts of the system, you can apply it to any target in the market.

We have tradable entity and then events about them.
the TradableEntity quote schema follows the following rules:
{entity_shema}{level}{adjust_type}Kdata
- entity_schema
TradableEntity class, e.g., Stock,Stockus.
- level
>>> for level in IntervalLevel:
print(level.value)
- adjust type

From above examples, you should know the unified way of recording data:
Schema.record_data(provider='your provider',codes='the codes')
Note the optional parameter provider, which represents the data provider. A schema can have multiple providers, which is the cornerstone of system stability.
Check the provider has been implemented:
>>> Stock.provider_map_recorder
{'joinquant': zvt.recorders.joinquant.meta.jq_stock_meta_recorder.JqChinaStockRecorder,
'exchange': zvt.recorders.exchange.exchange_stock_meta_recorder.ExchangeStockMetaRecorder,
'em': zvt.recorders.em.meta.em_stock_meta_recorder.EMStockRecorder,
'eastmoney': zvt.recorders.eastmoney.meta.eastmoney_stock_meta_recorder.EastmoneyChinaStockListRecorder}
You can use any provider to get the data, the first one is used by default.
One more example, the stock sector data recording:
>>> Block.provider_map_recorder
{'eastmoney': zvt.recorders.eastmoney.meta.eastmoney_block_meta_recorder.EastmoneyChinaBlockRecorder,
'sina': zvt.recorders.sina.meta.sina_block_recorder.SinaBlockRecorder}

- The parameter code[single], codes[multiple] represent the stock codes to be recorded
- Recording the whole market if not set code, codes
- This method will store the data locally and only do incremental updates
Refer to the scheduling recoding waydata runner
After recording the data of the whole market, you can quickly query the required data locally.

So, you should be able to answer the following three questions now:
- What data is there?
- How to record data?
- How to query data?
For more advanced usage and extended data, please refer to the data section in the detailed document.
Now we could write strategy basing on TradableEntity and EntityEvent. The so-called strategy backtesting is nothing but repeating the following process:
At a certain time, find the targets which matching conditions, buy and sell them, and see the performance.
Two modes to write strategy:
- solo (free style)
At a certain time, calculate conditions according to the events, buy and sell
- formal
The calculation model of the two-dimensional index and multi-entity
Well, this strategy is really too simple,sometimes naive, as we do most of the time.
When the report comes out, I look at the report. If the institution increases its position by more than 5%, I will buy it, and if the institution reduces its position by more than 50%, I will sell it.
Show you the code:

So, writing a strategy is not that complicated. Just use your imagination, find the relation of the price and the events.
Then refreshhttp://127.0.0.1:8050/,check the performance of your strategy.

Simple calculation can be done through query_data. Now it's time to introduce the two-dimensional index multi-entity calculation model.
Takes technical factors as an example to illustrate thecalculation process:
In [7]: from zvt.factors.technical_factor import *
In [8]: factor = BullFactor(codes=['000338','601318'],start_timestamp='2019-01-01',end_timestamp='2019-06-10', transformer=MacdTransformer())
two-dimensional indexDataFrame read from the schema by query_data.
