Will I need to make any adjustments to my Apple Stock holdings in Trademaster once it starts trading on a 4 for 1 stock split-adjusted basis this coming Monday 1 st Sept?
Yes. The quantity that you hold will change on your broker platform. Manually change this in Trademaster.
The average buy price will also need to be modified to a few decimal places to get the exact ‘Contract Note’ amount you currently have in TM
