Thank you for your valuable feedback and questions. Indeed some ETF are not showing although they are in the DB, needs checking. - An entry box is something to add, thanks for pointing out. - Real-time data from Tradier is costly. I was looking at IBKR and maybe I will switch to their API. But anyhow real-time is an overkill for now, maybe in the future. - Yes for entering orders, I use Tastyworks. I first validate the opportunities with real time data and enter the trade on the Tastyworks platform. - I actually made decent profits from selling Theta. The trick is to not overtrade and be ok if a week passes without making a trade. But my main investing strategy is a Buy and hold on a world index.
