Query regarding comments and json code in tradingview

Can I put this below json code in message box of an alert in tradingview, if there are mixed signals (buy, buy exit, sell, sell exit) in the single strategy for one stock itself…? Also what should be comment message in strategy.entry and strategy.exit or strategy.close for this mixed signals…?

{{exchange}}:{{ticker}}, order_type = {{strategy.order.comment}}, order_price = {{strategy.order.price}}, order_id = {{strategy.order.id}}
