Hello @moksha
Dhan does not own any prop trading firm, as it is strictly against our values. We focus solely on offering best product and tech experience to our users.
To answer your question on the implementation of Bracket Order, as mentioned in the post, Stop Loss Market orders are not allowed by the Exchange itself. This is the reason why we have implemented this system which in turn will make sure our users can benefit from BO as order type on Dhan. Moreover, we have kept the option to edit this Limit Price from the order modification screen as well.
For Trailing Stop Loss, we have an option to add TSL from Positions page directly - more details here. This is something that we have built after interacting with a lot of super traders.
Hope this helps!
