Hi, everyone!

I would like to plot when rsi crosses 40 line, but I'm failing in something and I don't know where is failing. Could you help me?

I paste:

Thank you in advance
Greetings from Spain, andaluz.

(1) You used Alarma.Set, but you have not defined any DataSeries for it. Actually Alarma[] only takes the values 0 or 1, so you would need to define a BoolSeries under properties:

public BoolSeries Alarma
{
get{return values[2];}
}

(2) Also you have not defined any DataSeries Upper40[]. If you add a new line, this does not create a dataseries, if you add a new plot, you would need to declare the dataseries under properties....

(3) There is no dataseries rsi[], but you have called this dataseries Default, so you need to use Default!

The code for line 102 should therefore read

Alarma.Set(Default[1] < 40 && Default[0] > 40);

which sets a Boolean value to Alarma....

Have not checked this, but you should be able to work it out...
