[Elmar]

Hello,

I am looking for a simple 3 bar (ohlc/4) WMA that will plot itself red when its value is less than 1 bar befoure and green when its more.

Thank you for your help dloomis , but unfortunately the WMA does not change the color it is permanently green. Maybe because i am still using eSignal 7.1 ?

[dloomis]

the ma doesnt change color, the bars change color

[Elmar]

Nope
Sorry neither do bars

[dloomis]

on the main menu bar, under Tools, do you have Formula wizard?

If not, v7.2 should be in your future from esignal.com/download

[Elmar]

Thank you D Loomis
I thought it was not working for the reason that i have a eSignal 7.1. Unfortunatelly i wont be able to download 7.2 for a while.

Actually dloomis, check Set #2:

vWMA3_of_OHLC4.getValue(MAStudy.MA) >= vWMA3_of_OHLC4.getValue(MAStudy.MA) 

Should read:

vWMA3_of_OHLC4.getValue(MAStudy.MA) >= vWMA3_of_OHLC4.getValue(MAStudy.MA, -1) 

Formula Wizard generated code will work in v7.1 and v7.0 (as long as you're not using any functions that didn't exist back then of course).

[dloomis]

Dion -

the formula wizard inserted OHLC/4 which had to be edited manulaly to OHLC4

the slash was a problem.

[Elmar]

I replaced the line in the code, but still the WMA gets plotted in green and the bars stay as they were
