Yes, It might not be the greatest invention, but, i feel it still helps, and i think there would be a lot of people that agree.
Not to compare with fyers or any other broker, but it is also a feature which comes built in with Original TV trading terminal. I’m sure Zerodha would implement in their own way here too, it just takes a bit more time.
Suppose, now i want to move my SL to the high of the prev candle or some previous low/high, then,
In the current setup, we would need to manually make note of the value and enter the value in the order window.
But, with trade by chart enabled, we can simply drag the SL to the level we want and automatically the values are entered and we just need to confirm on the order window.
Visually too it helps to know where our current SL and target levels are without having to mark them manually each time.
So, yes might not be a life changing feature, we can manage with the current features.
But, it certainly helps in terms of ease of use and visual represantation is what i feel.
