Hello T212 Technical,
I hope you will find and read this FEATURE.
When a user search for an equity(stock) in T212, if such equity is available in ISA, there should be a corresponding TICK at the side of such equity, this will allow a user to make a pre-informed decision of purchase in ISA or INV.
At the current, a user search for an equity in Investment account, the equity is available, then the user will have to switch to ISA account to search again, then the same equity is not available, user switch back to Investment account to buy.
Next equity is repeated, imagine switching back and forth for 100 equity ?
If a user search for an equity(shares or if you call it stock) there should be a BUY ISA , BUY INV (only if such equity is available in both ISA and INV), therefore a user that click BUY ISA will have the equity appear in his or her ISA account(if enough money in ISA to buy).
If the user click BUY INV(if enough money in INV), the equity should appear in his or her Investment account.
