calculating the state dimension

[Jushan-Randy-Chen]

Hi,

I've been going through one of the tutorials FinRL_PaperTrading_Demo, but I don't understand how the state dimension is calculated:

# amount + (turbulence, turbulence_bool) + (price, shares, cd (holding time)) * stock_dim + tech_dim
state_dim = 1 + 2 + 3 * action_dim + len(INDICATORS) * action_dim

I know that action_dim*3 is the number of actions needed for all 30 stocks in DJI, but what do the other parts refer to?
