Order Validation on Binance
Binance implements strict rules for symbol pair orders, including validations for minimum price, quantity, and total order value. These specifications are detailed in the Filters section of Binance's official API documentation.

Key considerations for order validation:
- Price filters (tickSize)
- Quantity filters (stepSize)
- Minimum notional value requirements
Code example for formatting amounts:
amount = 0.000234234
precision = 5
amt_str = "{:0.0{}f}".format(amount, precision)Rounding to step size:
from binance.helpers import round_step_size
amount = 0.000234234
tick_size = 0.00001
rounded_amount = round_step_size(amount, tick_size)Fetching Orders

Q: How do I check my Binance account balance using python-binance?

A: Use the create_test_order() method to validate your order parameters without actual execution.
Q: What are OCO orders?
A: OCO (One-Cancels-the-Other) orders combine a stop order with a limit order for automated trading strategies.
Q: How do I handle small balance conversions?
A: The transfer_dust() method helps convert small balances (dust) into BNB.
