1)Feedback and request for Forever Order & Alert is noted.
2)We do show existing position with horizontal line, the arrow you see is all past trades. Blue for longs & red for shorts.
3) We understand users have their own preferences for order type - Intraday or Delivery/Overnight. We wanted this to make it default by user preferences, but as of now trading-view library does not allow this. We are still figuring out some fixes around this.
4) Executed Stop Loss can be seen in orderbook or if the new entry is taken using Sl, you can see in positions or on chart.
