Instead of only offering direct debit, allow me to transer money via EFT or OSKO into a trading account and use those funds (if available) for my automated investments. Automated investments would be deferred if no funds are available.
This would allow me to change my investment amounts and frequency via my bank's interface without having to login to pearler.
This would also give me full control over money leaving my account rather than having to rely/trust a direct debit.
Also wouldnt need to update the direct debit authority if I ever change accounts (until I wanted to cash out..which would be rare/never).
