Hello Cliff,
First sorry for the delay in answering.
You don't get the buy on 5/22/01 because
it is the last bar in the data file and you reference
the previous bar SAR value in your formula:
buyPrice = ref (sar(), -1); sellPrice = ref( sar(), -1);
So the SAR is taken from the previous day and one
bar more is needed to trigger the signal.
But... very easy solution is to use:
buyPrice = sar(); sellPrice = sar();
buy = cross (high, buyPrice);
sell = cross (sellPrice , low);
without referencing one day back.
It will give you buy/sell signals exactly on that days
when SAR flips.
Best regards,
Tomasz Janeczko
