I am looking at RSI, 2-period.  I need the RSI to be declining for 4 days in a row..

At the 4th day, RSI needs to be < 10.  All days (1 - 4) must be declining.

Ken.

Answer found!  No need for work on your part.  Here is the request in context...

RSI2.1 < RSI2.1.1 < RSI2.1.2 < RSI2.1.3 < RSI2.1.4 AND
C > AVGC200 AND
RSI2.1 < 10 AND
RSI2.4 < 60

Thanks again.

There are actually two possibilities as to the settings of a 2-period Wilder's RSI. The RSI in the formula you have written does not use Wilder's smoothing. In this instance, you would need to modify your formula slightly to actually make all of the desired comparisons as each of these comparisons needs to be made individually instead of in series.

RSI2 < 10 AND RSI2 < RSI2.1.1 AND RSI2.1.1 < RSI2.1.2 AND RSI2.1.2 < RSI2.1.3 AND RSI2.1.3 < RSI2.1.4 AND RSI2.1.4 < 60 AND AVGC200 < C

The formula for a 2-period Wilder's RSI with Wilder's smoothing is quite a bit longer than just RSI2.

50 * (C - XAVGC3.1) / 2 / (.5000305 * (ABS(C - C1) + .5 * (ABS(C1 - C2) + .5 * (ABS(C2 - C3) + .5 * (ABS(C3 - C4) + .5 * (ABS(C4 - C5) + .5 * (ABS(C5 - C6) + .5 * (ABS(C6 - C7) + .5 * (ABS(C7 - C8) + .5 * (ABS(C8 - C9) + .5 * (ABS(C9 - C10) + .5 * (ABS(C10 - C11) + .5 * (ABS(C11 - C12) + .5 * (ABS(C12 - C13) + .5 * (ABS(C13 - C14)))))))))))))))) + 50

But a 2-period Wilder's RSI with Wilder's smoothing should be less than its previous value if and only if price is also less than its previous value. So we can check for the current value to be less than 10, the value of 4 bars ago to be less than 60 and then just compare closing prices for the parts in the middle.

50 * (C - XAVGC3.1) / 2 / (.5000305 * (ABS(C - C1) + .5 * (ABS(C1 - C2) + .5 * (ABS(C2 - C3) + .5 * (ABS(C3 - C4) + .5 * (ABS(C4 - C5) + .5 * (ABS(C5 - C6) + .5 * (ABS(C6 - C7) + .5 * (ABS(C7 - C8) + .5 * (ABS(C8 - C9) + .5 * (ABS(C9 - C10) + .5 * (ABS(C10 - C11) + .5 * (ABS(C11 - C12) + .5 * (ABS(C12 - C13) + .5 * (ABS(C13 - C14)))))))))))))))) + 50 < 10 AND C < C1 AND C1 < C2 AND C2 < C3 AND C3 < C4 AND 50 * (C4 - XAVGC3.5) / 2 / (.5000305 * (ABS(C4 - C5) + 1 / 2 * (ABS(C5 - C6) + 1 / 2 * (ABS(C6 - C7) + 1 / 2 * (ABS(C7 - C8) + 1 / 2 * (ABS(C8 - C9) + 1 / 2 * (ABS(C9 - C10) + 1 / 2 * (ABS(C10 - C11) + 1 / 2 * (ABS(C11 - C12) + 1 / 2 * (ABS(C12 - C13) + 1 / 2 * (ABS(C13 - C14) + 1 / 2 * (ABS(C14 - C15) + 1 / 2 * (ABS(C15 - C16) + 1 / 2 * (ABS(C16 - C17) + 1 / 2 * (ABS(C17 - C18)))))))))))))))) + 50 < 60 AND AVGC200 < C

Thanks for the alternatives, Bruce.  I will try them.

Thanks.
