Pre defined Stop loss and Trailing stop loss on chart

Rs 1 brokerage is great. But a pre defined stop loss is a must. Which we can set before taking trade. There is no time to manually type and trail especially on expiry days. I have incurred loss due to this issue. Please fix this. One click entry and exit directly on chart. Also drag and drop SL and TSL would be great. I have been using SAHI app which has great interface. I am switching just for Rs 1 brokerage. You should check out Sahi app and provide similar features. Really helpful. Plus I think there should be an option to remove grid pattern on chart. A nice clean chart is better.
