Adding stop loss to open position

Hi Guys,

Am newbie to Alpaca, yesterday I put my first trades via Tradingview trade panel, my stop loss positions have been cancelled overnight.

Please advise how to reinstate the stop loss to an open position. Note this is a paper trading account. your input will be much appreciated guys thanks.

cheers
tony

Guys I found my mistake, I had not tweaked the * all the time-in-force from Day to GTC so now am I have resolved this should be interesting to see how the paper trading progress.
