Yves,
Look more closely at your code. Specifically;
uptrend= IIf(Result,1,0) ;
downtrend= IIf(Result,1,0) ;
Notice that you have set uptrend and downtrend to the exact same value. Now looking at your IIf statement;
IIf( uptrend, colorViolet, IIf( downtrend, colorWhite, 0 ))
You are saying if uptrend use colorViolet, otherwise if downtrend use colorWhite, otherwise use 0.
Since uptrend and downtrend are set to the same value, whenever it is not uptrend it will not be downtrend either, and the result will therefore be 0.
Similarlly, anytime it is uptrend, it will also be downtrend. But, colorViolet will win since the 'true' branch gets first chance.
While you're fixing that, consider that the statement is unnecessary. There is no reason to say:
IIf(Result,1,0)
just say uptrend = Result;
Any non zero value is true. Whether Result holds a 5, a 1, or any other non zero value, they are all true. It is pointless to waste processing time converting the values to 1 unless you specifically need to use the values in some other mathematical equation.
Also, Haut will always be greater than Bas, so saying:
Ind[ i ] > Haut[ i ] AND Ind[ i ] > Bas[ i ]
is redundent. Just use:
Ind[ i ] > Haut[ i ].
