I have been trying to code the system called "Delphic Phenomenon" described in the book "Magic of Moving Averages" by Scott Lowry. For those not familiar with the system (very similar to Landry's Bow Tie), here is the description of the long and close long setups:
Long entry:
1) 18D SMA crosses above 40D SMA, then
2) Close rises above 18D SMA, then
3) Close drops below 18D SMA ( can go below 40D SMA), then
4) place a stop order at 18D SMA as long as 18D SMA > 40D SMA;
Long exit:
1) stop loss at 40D SMA, and
2) after 5 bars stop raised between 18D SMA and 40D SMA.

I have coded the following (Close instead of stop order assumed for next day entry at market open)

ma18:=Mov(C,18,S);
ma40:=Mov(C,40,S);
buy:=ma18>ma40 AND C<ma18;
sell:=ma18<ma40 AND C>ma18;
I:=Cum(Buy + Sell > -1) = 1;
Tr:=If(BarsSince(Buy OR I) < BarsSince(Sell OR I),1,-1);

LE:= Tr=1 AND C>ma18;
SE:= Tr=-1 AND C<ma18;
LX:= If(barssince(LE)<=5,C<ma40,C<ma18);
SX:= If(barssince(LE)<=5,C>ma40,C>ma18);
(latch omitted)

When plotted on charts, the system seems to give the appropriate entries and exits but maybe somebody may care to comment on the above code.
Thanks and regards.
