While trying to figure out the costs of trading with T212 I noticed a couple of things that make me a bit uncomfortable:
There are different charges for different stocks (other providers have 1 cost for going long and another for going short across all shares)
The SWAP costs for the same instrument change from day to day.
The 2nd of the 2 makes me very nervous cause it makes it impossible for me to forecast my costs, and costs are an element of the margin calculations (SWAP costs eat into the free funds bucket if I understand correctly). In other words I could be stopped out just because T212 decides to increase the SWAP charges on my positions and I have no way to check unless I manually check all overnight costs for all positions I hold.
Can somebody shed some light on this?
