The AB code is defined as:
// Vortex Indicator
// S&C Traders Tips Jan 2010
period = Param("Period", 14, 2 );
VMP = Sum( abs( H - Ref( L, -1 ) ), period );
VMM = Sum( abs( L - Ref( H, -1 ) ), period );
STR = Sum( ATR( 1 ), period );
VIP = VMP / STR;
VIM = VMM / STR;
Plot( VIP, "VI"+period+"+", colorBlue);
Plot( VIM, "VI"+period+"-", colorRed );
The system is defined as:
- Go long when the VI (or Dmi) goes from less than zero to greater than zero.
- Go short when the VI (or Dmi) goes from above zero to less than zero.
- All trades are placed "next day market on open."
That would translate to:
SetTradeDelays(1,1,1,1); // everything delayed 1 day
Buy = VIP > 0 AND Ref(VIP,-1) < 0;
BuyPrice = Open;
Sell = VIP < 0 and Ref(VIP,-1) > 0;
SellPrice = Open;
Short = Sell;
Cover = Buy;
That should do it - I've not tested this but it should be close.
