any block needs to be connected to at least on other block to work,
once per day will pass the "block activation" to the block next to it once per day ,
i would recommend you separate the trailing stop block like this ( [ If position ]=>[ Trailing Stop ] ) since you want the "trade" once per day not the "trailing stop"
string should work ! , I have used it before and its worked fine with me
