Coding an RSI move

[ssukhani@xxxxxxxx]

One of the major uses of the RSI is to identify the trend.

I use the indicator (set to 14 bars) to decide if I should be a buyer, seller, or a sideways trend watcher.

The concept is: 40 is a support in bull markets. A move above 60 signifies strength. (For bear markets this becomes 60 as resistance, and move below 40 as weakness)

The problem is, while the method is simple enough to apply visually, it is not easy to program it. This would qualify as an uptrend:
The RSI had moved above 60 in the last few bars. (strength) It is currently at 51. The last dip saw it reach 41, thus holding above the 40 support. (support)

I am unable to code this as a mechanical alert / indicator.

Any suggestions ?

Thanks.
