Your Buy statement is not a set of conditions, it is actually a
price
Assuming you want the entry to be based on the price of Open
on
Monday, here is example of how you can do it
dw =
dayofweek();
Monday = dw<ref(dw,-1); // in case Monday does not
exist use next day
Buy = cross( H, valuewhen( Monday, LondonOpen +
FiftyPips) );
BuyPrice = LondonOpen + FiftyPips;
