I am trying to create a condition of TSV or MS breaking the top of a 40 period Donc Channel. While I can do this from the chart using the parameter TSV greater than top of the channel with an offset of 1, I would like to set this so the condition is still true over a set period, say 3. This is to cover the scenario in which the indicator breaks out then ticks down below the channel top for a couple of bars.

Normally I would copy a formula into the Custom %True indicator then set the period as 3 but in this case I am unsure how to do it. Can you give a work around?

Well the Boolean Formula you would use in the Custom PCF % True Indicator should be fairly simple for MS.

MS > MAX(MS1.1,40)

As well as for something like a simple 18-period TSV.

TSV18 > MAX(TSV18.1,40)

But the formula would be quite long for something like an exponential 21-period TSV because you would need to make each comparison individually.

XAVG(TSV,21) > XAVG(TSV1.1,21) AND XAVG(TSV,21) > XAVG(TSV1.2,21) AND XAVG(TSV,21) > XAVG(TSV1.3,21) AND XAVG(TSV,21) > XAVG(TSV1.4,21) AND XAVG(TSV,21) > XAVG(TSV1.5,21) AND XAVG(TSV,21) > XAVG(TSV1.6,21) AND XAVG(TSV,21) > XAVG(TSV1.7,21) AND XAVG(TSV,21) > XAVG(TSV1.8,21) AND XAVG(TSV,21) > XAVG(TSV1.9,21) AND XAVG(TSV,21) > XAVG(TSV1.10,21) AND XAVG(TSV,21) > XAVG(TSV1.11,21) AND XAVG(TSV,21) > XAVG(TSV1.12,21) AND XAVG(TSV,21) > XAVG(TSV1.13,21) AND XAVG(TSV,21) > XAVG(TSV1.14,21) AND XAVG(TSV,21) > XAVG(TSV1.15,21) AND XAVG(TSV,21) > XAVG(TSV1.16,21) AND XAVG(TSV,21) > XAVG(TSV1.17,21) AND XAVG(TSV,21) > XAVG(TSV1.18,21) AND XAVG(TSV,21) > XAVG(TSV1.19,21) AND XAVG(TSV,21) > XAVG(TSV1.20,21) AND XAVG(TSV,21) > XAVG(TSV1.21,21) AND XAVG(TSV,21) > XAVG(TSV1.22,21) AND XAVG(TSV,21) > XAVG(TSV1.23,21) AND XAVG(TSV,21) > XAVG(TSV1.24,21) AND XAVG(TSV,21) > XAVG(TSV1.25,21) AND XAVG(TSV,21) > XAVG(TSV1.26,21) AND XAVG(TSV,21) > XAVG(TSV1.27,21) AND XAVG(TSV,21) > XAVG(TSV1.28,21) AND XAVG(TSV,21) > XAVG(TSV1.29,21) AND XAVG(TSV,21) > XAVG(TSV1.30,21) AND XAVG(TSV,21) > XAVG(TSV1.31,21) AND XAVG(TSV,21) > XAVG(TSV1.32,21) AND XAVG(TSV,21) > XAVG(TSV1.33,21) AND XAVG(TSV,21) > XAVG(TSV1.34,21) AND XAVG(TSV,21) > XAVG(TSV1.35,21) AND XAVG(TSV,21) > XAVG(TSV1.36,21) AND XAVG(TSV,21) > XAVG(TSV1.37,21) AND XAVG(TSV,21) > XAVG(TSV1.38,21) AND XAVG(TSV,21) > XAVG(TSV1.39,21) AND XAVG(TSV,21) > XAVG(TSV1.40,21)

The MS works fine but I do use the exponential setting on TSV as its more responsive. Please could you do the same formula with a TSV of 12 and 18 periods.

Please try the following for the 12-period exponential TSV.

XAVG(TSV,12) > XAVG(TSV1.1,12) AND XAVG(TSV,12) > XAVG(TSV1.2,12) AND XAVG(TSV,12) > XAVG(TSV1.3,12) AND XAVG(TSV,12) > XAVG(TSV1.4,12) AND XAVG(TSV,12) > XAVG(TSV1.5,12) AND XAVG(TSV,12) > XAVG(TSV1.6,12) AND XAVG(TSV,12) > XAVG(TSV1.7,12) AND XAVG(TSV,12) > XAVG(TSV1.8,12) AND XAVG(TSV,12) > XAVG(TSV1.9,12) AND XAVG(TSV,12) > XAVG(TSV1.10,12) AND XAVG(TSV,12) > XAVG(TSV1.11,12) AND XAVG(TSV,12) > XAVG(TSV1.12,12) AND XAVG(TSV,12) > XAVG(TSV1.13,12) AND XAVG(TSV,12) > XAVG(TSV1.14,12) AND XAVG(TSV,12) > XAVG(TSV1.15,12) AND XAVG(TSV,12) > XAVG(TSV1.16,12) AND XAVG(TSV,12) > XAVG(TSV1.17,12) AND XAVG(TSV,12) > XAVG(TSV1.18,12) AND XAVG(TSV,12) > XAVG(TSV1.19,12) AND XAVG(TSV,12) > XAVG(TSV1.20,12) AND XAVG(TSV,12) > XAVG(TSV1.21,12) AND XAVG(TSV,12) > XAVG(TSV1.22,12) AND XAVG(TSV,12) > XAVG(TSV1.23,12) AND XAVG(TSV,12) > XAVG(TSV1.24,12) AND XAVG(TSV,12) > XAVG(TSV1.25,12) AND XAVG(TSV,12) > XAVG(TSV1.26,12) AND XAVG(TSV,12) > XAVG(TSV1.27,12) AND XAVG(TSV,12) > XAVG(TSV1.28,12) AND XAVG(TSV,12) > XAVG(TSV1.29,12) AND XAVG(TSV,12) > XAVG(TSV1.30,12) AND XAVG(TSV,12) > XAVG(TSV1.31,12) AND XAVG(TSV,12) > XAVG(TSV1.32,12) AND XAVG(TSV,12) > XAVG(TSV1.33,12) AND XAVG(TSV,12) > XAVG(TSV1.34,12) AND XAVG(TSV,12) > XAVG(TSV1.35,12) AND XAVG(TSV,12) > XAVG(TSV1.36,12) AND XAVG(TSV,12) > XAVG(TSV1.37,12) AND XAVG(TSV,12) > XAVG(TSV1.38,12) AND XAVG(TSV,12) > XAVG(TSV1.39,12) AND XAVG(TSV,12) > XAVG(TSV1.40,12)

And the following for the 18-period exponential TSV.

XAVG(TSV,18) > XAVG(TSV1.1,18) AND XAVG(TSV,18) > XAVG(TSV1.2,18) AND XAVG(TSV,18) > XAVG(TSV1.3,18) AND XAVG(TSV,18) > XAVG(TSV1.4,18) AND XAVG(TSV,18) > XAVG(TSV1.5,18) AND XAVG(TSV,18) > XAVG(TSV1.6,18) AND XAVG(TSV,18) > XAVG(TSV1.7,18) AND XAVG(TSV,18) > XAVG(TSV1.8,18) AND XAVG(TSV,18) > XAVG(TSV1.9,18) AND XAVG(TSV,18) > XAVG(TSV1.10,18) AND XAVG(TSV,18) > XAVG(TSV1.11,18) AND XAVG(TSV,18) > XAVG(TSV1.12,18) AND XAVG(TSV,18) > XAVG(TSV1.13,18) AND XAVG(TSV,18) > XAVG(TSV1.14,18) AND XAVG(TSV,18) > XAVG(TSV1.15,18) AND XAVG(TSV,18) > XAVG(TSV1.16,18) AND XAVG(TSV,18) > XAVG(TSV1.17,18) AND XAVG(TSV,18) > XAVG(TSV1.18,18) AND XAVG(TSV,18) > XAVG(TSV1.19,18) AND XAVG(TSV,18) > XAVG(TSV1.20,18) AND XAVG(TSV,18) > XAVG(TSV1.21,18) AND XAVG(TSV,18) > XAVG(TSV1.22,18) AND XAVG(TSV,18) > XAVG(TSV1.23,18) AND XAVG(TSV,18) > XAVG(TSV1.24,18) AND XAVG(TSV,18) > XAVG(TSV1.25,18) AND XAVG(TSV,18) > XAVG(TSV1.26,18) AND XAVG(TSV,18) > XAVG(TSV1.27,18) AND XAVG(TSV,18) > XAVG(TSV1.28,18) AND XAVG(TSV,18) > XAVG(TSV1.29,18) AND XAVG(TSV,18) > XAVG(TSV1.30,18) AND XAVG(TSV,18) > XAVG(TSV1.31,18) AND XAVG(TSV,18) > XAVG(TSV1.32,18) AND XAVG(TSV,18) > XAVG(TSV1.33,18) AND XAVG(TSV,18) > XAVG(TSV1.34,18) AND XAVG(TSV,18) > XAVG(TSV1.35,18) AND XAVG(TSV,18) > XAVG(TSV1.36,18) AND XAVG(TSV,18) > XAVG(TSV1.37,18) AND XAVG(TSV,18) > XAVG(TSV1.38,18) AND XAVG(TSV,18) > XAVG(TSV1.39,18) AND XAVG(TSV,18) > XAVG(TSV1.40,18)

Thats great, thank you.
