Franco/All:
This makes an interesting little trading system. Play with it. Some of the
equity curves are quite smooth. Some are not.

Chg = Optimize("Chg",3.5,0.5,6,0.5);
res = Ref(Peak(H, Chg, 1), -1);
sup = Ref(Trough(L, Chg, 1), -1);
Plot(C,"Close",1,64);
Plot(res,"res",6,1);
Plot(sup,"sup",4,1);
Buy = H > res;
Sell = L < sup;
Buy = ExRem(Buy,Sell);
Sell=ExRem(Sell,Buy);

Franco:
What a clever set of indicator lines!! Nice idea.
I modified the code as follows:
Chg = 5;
res = Ref(Peak(H, Chg, 1), -1);
sup = Ref(Trough(L, Chg, 1), -1);
Plot(res,"res",6,1);
Plot(sup,"sup",4,1);
What is the change percent (Chg) that you think is "best"?? I see you used
2.5.

Tomasz,
look, please, at the attached chart. You will see two
lines wich represent resistance and support
respectively. They are obtained by the formulas:
res = ref(Peak(H, 2.5, 1), -1);
sup = ref(Trough(L, 2.5, 1), -1);
My purpose is to use them depending on level of the
last closing price. Since a support, once broken,
became a resistance and vice versa, I need a formula
wich is able to find the lowest (and nearest) peak or
trough, but higher than the last closing price.
On the attached chart, the nearest resistance is,
actually, as you can see, an old support previously
broken (yellow line).
All that is for long trades, the opposite for short,
obviously.
Hoping to have been more clear,
best regards and thanks in advance
Franco
