Heads up for people using etrade and trying to figure out margin effects either using Portfolio Margin Analyzer, Margin Calculator or Power Etrade previews and how a trade will effect Remaining Margin Buying Power.
Etrades margin calculations for how a trade will affect buying power are often completely wrong.
They calculate as if the trade stood alone. Not taking into account their algorythm for margin calculations.
Not taking into account if you have a short naked put and you buy a put to create a vertical spread.
I've documented this several times and have discussed it with them.
They admit it but they also admit that it is unilikely anything wiill change.
I have no answer to what you can do to calculate how a trade will effect your margin.
Just understand that you may not get accurate information from a trade until after it is actually executed.
