Auto buy and sell feature?

Would it be possible to add the facility to buy and sell at preset thresholds automatically?

Eg. If a stock Iā€™m watching drops to X buy X shares.

On the flip side, if stock Iā€™m invested in achieves X Sell X number of shares at that rate.

I check the app everyday, but it would be good to have these features so not to miss out on opportunities.

Even if it was just an alert / push notification that I then accepted / validated it would be really useful.
