The spreadsheet is a basic spreadsheet that contains 225 cells (45 rows and 5 columns). While the ability to name cells and ranges are not present (hopefully the next version will provide such ability), classical spreadsheet analysis is present: Sum, Minimum, Maximum, Average (Mean), and filling cells with a certain value. We also have the option of using relative or absolute cell references. In spreadsheet mode, pretty much every function is accessed through the Option menu. The fx-991 EX Classwiz allocates 1,700 bytes for the spreadsheet function (I think this is exclusive memory set aside for this mode). I did not have the chance to physically try that calculator but going through the PDF manual, it seems to have a nice feature regarding engineering units. I am not sure if I understand correctly, but looking at their example it looks like when we have a result like 1.234e3, we may press ENG to show 1234e0 or we may press SHIFT ENG to show 0.001234e6 for example.

We may also do that apparently with showing engineering symbols like u, n, p, M, G, etc. I know you may say that in our head it should be easy to move the dot by three to left or right and set the exponent.

Please see the image link so you can better understand what I am talking about, perhaps you can help me understand this: I will appreciated your prompt response. Anonymous Let me explain the basic principle how most Forex systems work. They are tuned up to work in a specific market condition. They often make money in a trending market, but loose money in a choppy market. It is not a problem as long as the market is trending and the system is making more money than it loses.

Such a system can be profitable for several months and you would be happy with it. PREPARE FOR THE WORST. Market change over time. A well designed system starts with trend analysis to stay away from potentially losing trades. There are two problems of how a Forex system recognizes the trend.

PROBLEM: FALSE 'STRONG TREND' INDICATION. The system responds only to immediate price action. An explosive price movement that is usually the result of news release is tempting people to jump in and make a profit.
