Choose the right device for the job
Any modern phone can place an order, but screen size decides how much analysis you can realistically do. A phone is best for monitoring and managing existing positions; a tablet is a workable analysis device; a laptop remains the right place to build a plan.
Connectivity is a risk parameter
A dropped connection does not close your positions, but it does stop you managing them. Always attach a stop loss on the server side rather than planning to close manually, and prefer a stable Wi-Fi connection for anything larger than a test position.
Alerts instead of screen time
Configure price alerts at your entry, invalidation and target levels. This replaces constant chart watching with a small number of decision moments, which improves both execution quality and battery life.
Frequently asked questions
Order routing speed is essentially the same because execution happens on the server. The practical difference is how quickly you can analyse and enter the order correctly on a small screen.
