Thanks, with setf(plotMode,PL_ALL) and the trick of plot equity is good but the lines are discontinuous.

There is strange because :

while(Name = (loop(Assets)))
{
asset(Name);
plot(Name,priceClose(),NEW,CYAN);

--> The lines are discontinuos too but if I plot at the end of my code there is no problema with:

asset("EUR/USD);
plot("EUR/USD",priceClose(),NEW,CYAN)

--> The line is correct, No problem.
