// Current Version 1.1 on 31.07.2008.

///////////////////////////////////////////////////////////
///// Major changes done from previous version 1.0 : //////

// The method of pivot definition is changed. 
// Now it does not use zig() or related functions anywhere.

// Stoploss line error, that it moves in both directions after a position is taken,
// is removed. Now stoploss lines are unidirectional.

// To protect profit on long positions, SELL is triggered either when trailing buy stop
// is hit OR when previous lower pivot is cracked. Fresh long position will be initiated 
// if uptrend continues after previous high pivot is cracked.   

///////////////////////////////////////////////////////////


// This is simple YET powerful pivot based trading system.
// Used only for intraday. Not suitable for EOD data.
// Designed for continuous trading. i.e. short=sell and cover=buy
// When long, watch crack of close in green line ONLY. Ignore red line.
// When short, watch crack of close in red line ONLY. Ignore green line.
// You will have to tweak the parameters as per your trading style.

// Warning : 	I have tried to develop this method from Saint's Pivot Based System (www.traderji.com) 
// 		However, it is very well possible that its performance is not as per actual system
// 		suggested by Saint due to programming errors and inadequate knowledge level at my end.
// Warning : 	Traders are advised to trade on their own, knowing very well that it is their money.
