Guys… need some help here.
I´m trying to develop a Custom Study of 3 RSI lines cross … that enters a Buy Order if Line 2 crosses line 3 from bottom … but only if the “value” of lines (RSI) is below 30 … don´t know how to specify this RSI value/number … those lines are already calculated and part of the graph studies.
Any help? I´m starting but don´t know how to progress…
Thanks in advance.
Posting part of my study:

if (sc.CrossOver(line2, line3) == CROSS_FROM_BOTTOM)
{
// mark the crossover on the chart
bullish[sc.Index] = 1;
// Create a market order and enter long.
s_SCNewOrder order;
order.OrderQuantity = 1;
order.OrderType = SCT_ORDERTYPE_MARKET;
sc.BuyEntry(order);
}

No one can help?

You asked at 10pm ET during a holiday week on a forum that does not have a ton of SC programmers; a little patience is required.

I did not know how to do this, but I went to the very thorough SC documentation, and tracked this down in less than 3 minutes:
