comment Standard way to represent trend in an a-dimensional way
Your question is very unclear. How can "trend of A equal trend of B" and "trend of B is greater than trend of A"? The product prices aren't important if you're measuring how much they impact profit; you want to compare profit margin. You need to explain why a simple percent change isn't adequate.

comment Normally Distributed Returns Become Leptokurtic Due to Compounding
@jessica: NORM.INV(RAND(),0,1) yields numbers roughly between -3/+3. That's not -3% to +3%; it's -300% to +300%. Hence my comment that your "returns" are huge.

comment Normally Distributed Returns Become Leptokurtic Due to Compounding
1) Your simulated "returns" are huge (the return will be >100% more than 10% of the time). 2) What did you expect? Compounding is exponential, so long tails aren't surprising (especially with huge returns).

comment where can i get data for foreign exchange order flow
The foreign exchange market is decentralized. There's no one place you can go to get the total order flow. You could get order flow for foreign exchange futures though.

This question is off-topic because it is spam, just like it was spam on NP.

It's a flow, not a stock; like the difference between income and wealth.

comment Microstructure effects for a market maker?
@statquant: of course you have something valuable to share. You're here because you do this for a living. So you could ask a question where the answer would be directly related to how you make money. Then you answer your own question, providing details on what gives you an edge over other market participants.

comment Microstructure effects for a market maker?
@statquant: That's rather hypocritical coming from someone who has yet to share valuable information themselves.
