Prevent "Not enough shares to sell" error

[siropkin]

Sometimes you can see that bot can't sell stocks because of this error: Not enough shares to sell.

Log example:

[2024-11-01 11:28:53] [INFO]    WD > Decision: sell with amount $1.0
[2024-11-01 11:28:53] [DEBUG]   Function: order_sell_fractional_by_price, Parameters: ('WD', 1.0), Attempt: 1/3, Result: {'detail': 'Not enough shares to sell.'}
[2024-11-01 11:28:53] [ERROR]   WD > Error selling: Not enough shares to sell.

It will be great if bot will prevent it before sell attempt.

One of the possible solutions will be filter decisions in adjust_decisions():

# Adjust decisions based on trading parameters
def adjust_decisions(decisions):
    sell_decisions = [
        decision for decision in decisions
        if decision['decision'] == "sell" and MIN_SELLING_AMOUNT_USD <= decision['amount'] <= MAX_SELLING_AMOUNT_USD
    ]
    buy_decisions = [
        decision for decision in decisions
        if decision['decision'] == "buy" and MIN_BUYING_AMOUNT_USD <= decision['amount'] <= MAX_BUYING_AMOUNT_USD
    ]
    hold_decisions = [decision for decision in decisions if decision['decision'] == "hold"]
    return sell_decisions + buy_decisions + hold_decisions

But it's not a garanty way.
