Hi Abby,
This is the computation in excel that I use for philstock... I noticed this while taking the trading history to excel and getting computations on how to compute the actual commision/fee. i like it precise
for buy:
net amount = # of shares X price x (1 + 0.004464 )
this is the multiplier I get now... it was much cheaper a month ago... It was around 0.003192
for sell
net amount = # of shares X price x (1 - 0.008192 )
hope this helps!
