Helo jcl, how do I code Heiken-Ashi Indicator in zorro s?

http://www.dailyfx.com/forex/education/t..._Indicator.html

how would I convert something like this pseudo code into zorro lite-c code?

===================
== Entry conditions
===================
LongEntryCondition = ((Open(9) > HeikenAshiLow(17)) Or (ATR(76) Crosses Below ATR(67)))
ShortEntryCondition = ((Open(9) < HeikenAshiHigh(17)) Or (ATR(76) Crosses Above ATR(67)))


===================
== Entry orders
===================
-- Long entry
if LongEntryCondition is true {
Reverse existing order (if any) and Buy on open at Market;
Stop Loss = 98 pips;
}

-- Short entry
if ShortEntryCondition is true {
Reverse existing order (if any) and Sell on open at Market;
Stop Loss = 98 pips;
}

Pseudo code is easily converted to Zorro Code. For Haikin Ashi:

Close = (Open+High+Low+Close)/4
Open = [Open (previous bar) + Close (previous bar)]/2
High = Max (High,Open,Close)
Low = Min (Low,Open, Close)

==>

vars Close = series((priceOpen()+priceHigh()+priceLow()+priceClose())/4);
vars Open = series((priceOpen(1)+priceClose(1))/2);
vars High = series(max(priceHigh(),max(priceOpen(),priceClose())));
vars Low = series(min(priceLow(),min(priceOpen(),priceClose())));

Only take care to count correctly the number of brackets.
