Portfolio as subset of stocks data

[FabioMD1972]

Hi,
I'm quite new on FinRL.
This is my usecase:

• suppose to collect DOW 30 data and use it to build the environment
• within this environment I want to trade only on a (fixed) subset of ticks lets says [AAPL, AXP]

The question is how I have to instantiate the StockTradingEnv class?

`
from finrl.meta.env_stock_trading.env_stocktrading import StockTradingEnv
....

env_kwargs = {
"hmax": 100,
"initial_amount": 1000000,
"num_stock_shares": num_stock_shares,
"buy_cost_pct": buy_cost_list,
"sell_cost_pct": sell_cost_list,
"state_space": state_space,
"stock_dim": stock_dimension,
"tech_indicator_list": INDICATORS,
"action_space": stock_dimension,
"reward_scaling": 1e-4
}

e_train_gym = StockTradingEnv(df = train, **env_kwargs)
`

I look at a lot of examples but I can't find the solution.

Thank you, F.

Just filter your train dataframe just after you read it before calculating any dimensions, keep only the subset of ticks you want.
