What it does here...
- Stores shared trading strategy state for the bots.
- Tracks open orders, filled orders, canceled orders, and profit/loss.
- Saves and reloads strategy data from a local JSON state file.
- Calculates inventory balance between token holdings and SWAP.HIVE.
- Adjusts buy/sell quotes based on inventory imbalance.
- Widens quotes during higher volatility.
- Protects minimum profit spacing between buy and sell quotes.
- Suggests longer order patience when liquidity is low.
- Decides when old or badly priced orders should be canceled.
- Provides a simple fallback quote generator for buy/sell prices and quantities.
