It's too much work for me to try and test the solution I propose, because you did not provide a reproducible example. That said, try this: add.signal(qs.strategy, name = "sigFormula", arguments = list( columns = c("Close","SMA10"), formula = "(Close >= SMA10.Cross) & lag(Close < SMA10.Cross)", cross = FALSE), label = "CrossedAbove")

Hi, I am using the following line to add signals: add.signal( qs.strategy,name = "sigFormula", arguments = list( columns = c("Close","SMA10"), formula = "(Close >= SMA10.Cross)",cross = FALSE ), label = "CrossedAbove" ) and want to add another condition: Previous Close < Previous SMA10 I have tried the one below: qs.strategy,name = "sigFormula", arguments = list( columns = c("Close","SMA10"), formula = "(Close >= SMA10) & (Close[nrow(Close) - 1] < SMA10[nrow(SMA10)-1])",cross = FALSE ), label = "CrossedAbove" ) But It does not work. Any help will be appreciated. Thanks.
