Got market Limit issue in Bracket Order (Bracket order are not what you think really are, read it before you incure loss)

I recently manually placed a bracket order from my desktop, specifying the entry and exit values along with a limit value. However, the order was executed at the current LTP (Last Traded Price) of the candle instead of the limit value I set. I reached out to Paytm for clarification, and they informed me that the limit value should be higher than the LTP. This raises a concern: if this is the case, then what is the purpose of a bracket order? It seems I can’t effectively place an order based on my desired entry, exit, and target conditions.

I’m also interested in knowing whether there’s an alternative approach to achieving my trading goals, both with and without utilizing APIs. Any insights or suggestions would be greatly appreciated.
