Could you help me to create the following conditions?
1. Elder Force Index.
a. Daily.
Force Index smoothing by 2
Force Index 2 (Today - Now) > Force Index 2 (Yesterday)
Force Index smoothing by 13
Force Index 13 (Today - Now) > Force Index 13 (Yesterday)
b. Weekly.
Force Index smoothing by 2
Force Index 2 (This week - Now) > Force Index 2 (Last week)
Force Index smoothing by 13
Force Index 13 (This week - Now) > Force Index 13 (Last week)
Is there any general formulas that I can calculate the value Force Index smoothing by m of the n th day ago (or the n th week ago)?
2. Stochastics 5 %k3.
a. Daily.
Stochastics 5 %k3 (Today) > [Stochastics 5 %k3 (Yesterday) + 20]
b. Weekly.
Stochastics 5 %k3 (This week) > [Stochastics 5 %k3 (Last week) + 20]
Is there a fomula that I can calculate the value of Stochastics 5 %k3 of the n th day ago (or the n th week ago)?
Thank you.

Daily and weekly formulas are the same in TC2000 version 12.3. The only difference is the Time Frame setting of that formula. You can change the time frame using the Time Frame drop-down menu when you create or edit a formula. You can also set the time frame of a formula to something other than its default when using a formula as a WatchList Column or EasyScan Condition by editing the WatchList Column or EasyScan.
A Condition Formula for the 2-Period Force Index increasing could be written as:
(C - C1) * V > ((C1 - C2) * V1 + 1 / 3 * ((C2 - C3) * V2 + 1 / 3 * ((C3 - C4) * V3 + 1 / 3 * ((C4 - C5) * V4 + 1 / 3 * ((C5 - C6) * V5 + 1 / 3 * ((C6 - C7) * V6)))))) / (3 / 2 - 1 / 2 * (1 / 3) ^ 5)
A Condition Formula for the 13-Period Force Index increasing could be written as:
(C - C1) * V > .142996 * ((C1 - C2) * V1 + 6 / 7 * ((C2 - C3) * V2 + 6 / 7 * ((C3 - C4) * V3 + 6 / 7 * ((C4 - C5) * V4 + 6 / 7 * ((C5 - C6) * V5 + 6 / 7 * ((C6 - C7) * V6 + 6 / 7 * ((C7 - C8) * V7 + 6 / 7 * ((C8 - C9) * V8 + 6 / 7 * ((C9 - C10) * V9 + 6 / 7 * ((C10 - C11) * V10 + 6 / 7 * ((C11 - C12) * V11 + 6 / 7 * ((C12 - C13) * V12 + 6 / 7 * ((C13 - C14) * V13 + 6 / 7 * ((C14 - C15) * V14 + 6 / 7 * ((C15 - C16) * V15 + 6 / 7 * ((C16 - C17) * V16 + 6 / 7 * ((C17 - C18) * V17 + 6 / 7 * ((C18 - C19) * V18 + 6 / 7 * ((C19 - C20) * V19 + 6 / 7 * ((C20 - C21) * V20 + 6 / 7 * ((C21 - C22) * V21 + 6 / 7 * ((C22 - C23) * V22 + 6 / 7 * ((C23 - C24) * V23 + 6 / 7 * ((C24 - C25) * V24 + 6 / 7 * ((C25 - C26) * V25 + 6 / 7 * ((C26 - C27) * V26 + 6 / 7 * ((C27 - C28) * V27 + 6 / 7 * ((C28 - C29) * V28 + 6 / 7 * ((C29 - C30) * V29 + 6 / 7 * ((C30 - C31) * V30 + 6 / 7 * ((C31 - C32) * V31 + 6 / 7 * ((C32 - C33) * V32 + 6 / 7 * ((C33 - C34) * V33 + 6 / 7 * ((C34 - C35) * V34 + 6 / 7 * ((C35 - C36) * V35 + 6 / 7 * ((C36 - C37) * V36 + 6 / 7 * ((C37 - C38) * V37 + 6 / 7 * ((C38 - C39) * V38 + 6 / 7 * ((C39 - C40) * V39 + 6 / 7 * ((C40 - C41) * V40 + 6 / 7 * ((C41 - C42) * V41 + 6 / 7 * ((C42 - C43) * V42 + 6 / 7 * ((C43 - C44) * V43 + 6 / 7 * ((C44 - C45) * V44 + 6 / 7 * ((C45 - C46) * V45)))))))))))))))))))))))))))))))))))))))))))))
A Condition Formula for a Simple Stochastic 5,3 %K increasing by more than 20 between the previous bar and the current bar can be written as:
STOC5.3 > STOC5.3.1 + 20
Checking for n-bars ago ago is simply a matter of adding 1 to all of the bars ago parameters in the formula. In the case of the Stochastic, that is relatively easy to do. A 1-bar ago version of the above would just be:
STOC5.3.1 > STOC5.3.2 + 20
The technique is the same for the Force Index, but it is obviously more tedious because you have to increment far more bars ago parameters.
Another option would be to add a 1-Period Simple Moving Average to the indicator of interest with the Offset of that moving average set to the number of bars ago you want to check. You can then click on the moving average and select Create Scan Condition or Show Values in WatchList. This allows you to create conditions or display values based on past values of the indicator without creating any formulas.

Can you provide the formula below for a 3-Period Elder Force Index? Thanks.
A Condition Formula for the 2-Period Force Index increasing could be written as:
(C - C1) * V > ((C1 - C2) * V1 + 1 / 3 * ((C2 - C3) * V2 + 1 / 3 * ((C3 - C4) * V3 + 1 / 3 * ((C4 - C5) * V4 + 1 / 3 * ((C5 - C6) * V5 + 1 / 3 * ((C6 - C7) * V6)))))) / (3 / 2 - 1 / 2 * (1 / 3) ^ 5)

The 3 period Elder's Force Index can be written as follows in TC2000 v17+.
XAVG((C - C1) * V, 3)
Or as follows in earlier versions of TC2000.
.50048876 * ((C - C1) * V + .5 * ((C1 - C2) * V1 + .5 * ((C2 - C3) * V2 + .5 * ((C3 - C4) * V3 + .5 * ((C4 - C5) * V4 + .5 * ((C5 - C6) * V5 + .5 * ((C6 - C7) * V6 + .5 * ((C7 - C8) * V7 + .5 * ((C8 - C9) * V8 + .5 * ((C9 - C10) * V9))))))))))

Thanks for this Bruce.
I'm using V18..., but would like to have the indicatator indicate when the 3-period Elder's Force index is greater than previous period. That is, a condition formula for the 3-Period Force Index increasing over the last period. Hope you can help. Thanks again.

Please try the following.
(C - C1) * V > XAVG((C1 - C2) * V1, 3)
