One thing I advise those new to stocks is this: never use Banks to trade Securities for one simple reason, stock-broking is not their core business! Thus, they won't/haven't suitably invested in their staff...or their systems!
Stockbroking: earns them 1.2% margin (low volumes)
Credit/loans: earns them at least 12% margin (high-higher volumes)
Think of it this way: Investment banks and pure- stockbrokers are the only one who may give you the attention you deserve- they have invested in systems and people (these are the engine parts of any business)
Key thing is build a relationship with them (brokerage) and it will blossom. Wazuans will tell you that.
Online platforms, good. Have to know what you are doing though so as to avoid temperamental trading.
I went into the (Ferry) industry knowing the same thing I knew with all other businesses I went into- Nothing. Then I built it from there. - Sheldon Adelson (Titans at the Table- Giants of Macau)
