pardon my naivete: If I have $25K and I'm trading 18 crude oil contracts at a time on intraday margin, what would I owe my broker on interest for using that margin? I have read the warnings from the pros here about maxing intraday margins, but, there is a possibility of a profit to be made, correct? The dollar amount in the profit or losses would be similar. If I made $360 profit on a 0.02 cent move then I could also lose $360 on a 0.02 move against me correct, or could the losses be more? Also, do sizes like 18 contracts draw market makers to trigger your trail stops, anybody experienced this? I read a thread here where someone said its real but wasn't sure if this dude was being paranoid. Thank you Elite Trader nation. I hope to learn, and trade for a long time.
