Are there any trading platforms that allow something like the following? Ability to run a script that operates on multiple tickers with input parameters per ticker. The script can then alert you to certain setup, which would have an entry price, stop and profit Target. I don't want to automate placing the order, just entering it into an order form for review and ultimately I would place the order and manage the trade. I understand that I could write a custom interface and use alpaca or some other trade api, but I'm hoping to avoid that and leverage an existing trade platform for managing the trade.
For Futures: My experience has been with Multicharts for such automation while using the Powerlanguage version. You can try the demo here: https://optimusfutures.com/Platforms/MultiCharts.php As far as I know, Motivewave has an SDK and also has this ability https://optimusfutures.com/Platforms/MotiveWave.php I hope this helps.
