How are the price limits determined?

Limits are determined by the stock board and ST status. For example, the Main Board has a 10% limit, which reduces to 5% for ST stocks. ChiNext and STAR Market use 20%, while BSE uses 30%.

Can I check the standard limits for a specific board?

Yes, you can use the `get_board_configuration` tool to retrieve the standard fluctuation percentages for any recognized market board.

Does this tool handle Chinese rounding rules?

Yes, the `calculate_price_limits` tool implements the specific discretization and rounding logic required for the Chinese market to ensure valid price ticks.
