While the interface and user experience is great, I have a suggestion to enhance this.
If you could somehow allow the bunching or clubbing of holdings and positions, it would help identify, analyse and decide faster. One of the example scenarios would be in cases of multiple straddles and strangles of the same instrument type. If one were able to mark the related trades and triggers, it would really be a breeze to exit or modify positions.
If you could even expose this to be used from the web / mobile app, it will allow for easier tracking of the positions in Holdings & Equities.
Maybe if it cannot be tagged, then would it be possible to individually set the sequence in the list of positions to give some degree of bunching.
