Download Link From John Wiley for BWSwTS 2nd Ed. Source Code
I have had a few emails stating the link in the book wasn’t working correctly so here is the one I use and it seems to work fine. Please let me know if you have any problems. The password is in the back of the book.

King Keltner Source Code
Looking for a trend follower – give this one a try!
[LegacyColorValue = true];
{King Keltner Program
King Keltner by George Pruitt -- based on trading system presented by Chester Keltner
-- an example of a simple, robust and effective strategy}
Inputs: avgLength(40),atrLength(40);
Vars: upBand(0),dnBand(0),liquidPoint(0),movAvgVal(0);
movAvgVal = Average((High + Low + Close)/3.0,avgLength);
upBand = movAvgVal + AvgTrueRange(atrLength);
dnBand = movAvgVal - AvgTrueRange(atrLength);
{Remember buy stops are above the market and sell stops are below the market
-- if the market gaps above the buy stop, then the order turns into a market order
vice versa for the sell stop}
if(movAvgVal > movAvgVal[1]) then Buy ("KKBuy") tomorrow at upBand stop;
if(movAvgVal < movAvgVal[1]) then Sell("KKSell")tomorrow at dnBand stop;
liquidPoint = movAvgVal;
if(MarketPosition = 1) then Sell tomorrow at liquidPoint stop;
if(MarketPosition =-1) then BuyTocover tomorrow at liquidPoint stop;

Developing Winning Trading Systems…. being translated into Chinese in 2014
Just got word the 2nd edition is being published in Chinese.
One System From The Book
Just wanted to bring one of the systems that I developed for the book to everybody’s attention. This is a simple system that puts on two contracts and peels one off after a certain profit and then lets the other one ride. Its a mini-Russell system. Full code is disclosed in the book – source code can be imported into other applications. The object of this code is to demonstrate multiple contracts and money management techniques. Remember –
THERE IS A SUBSTANTIAL RISK OF LOSS IN TRADING. IT IS IN THE NATURE OF COMMODITY TRADING THAT WHERE THERE IS THE OPPORTUNITY FOR PROFIT, THERE IS ALSO THE RISK OF LOSS. COMMODITY TRADING INVOLVES A CERTAIN DEGREE OF RISK, AND MAY NOT BE SUITABLE FOR ALL INVESTORS. PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS.
THE HIGH DEGREE OF LEVERAGE THAT IS FOUND IN FUTURES (BECAUSE OF SMALL MARGIN REQUIREMENTS) CAN WORK AGAINST YOU AS WELL AS FOR YOU. I.E. YOU CAN HAVE LARGE LOSSES AS WELL AS LARGE GAINS.
This Code Uses A Loop To Calculate Buy/Sell Levels Based on Current Position
Instead of doing this:
if currentshares = LTT then begin
buy("B-20A.5") LTT shares next bar highest(h,20)[BB] + (0.5*N) or higher;
buy("B-20A 1") LTT shares next bar highest(h,20)[BB] + (1.0*N) or higher;
buy("B-20A1.5") LTT shares next bar highest(h,20)[BB]+ (1.5*N) or higher;
end;
if currentshares = LTT * 2 then begin
buy("B-20B 1") LTT shares next bar highest(h,20)[BB] + (1.0*N) or higher;
buy("B-20B1.5") LTT shares next bar highest(h,20)[BB] + (1.5*N) or higher;
end;
if currentshares = LTT * 3 then
buy("B-20C1.5") LTT shares next bar highest(h,20)[BB] + (1.5*N) or higher;
end;
Just do this:
for iCnt = 0 to 3
begin
if lastTradeLoser then
begin
if mp <> -1 and currentContracts = iCnt * lotSize then
begin
buyPrice = hh20 + iCnt * N/2;
end;
end;
end;
if lastTradeLoser then
begin
if currentContracts < 4 * lotsize then Buy ("Turtle20Buy") lotSize contracts next bar at buyPrice stop;
end;
Instead of having multiple buy orders at different levels -simply change your buy levels using the for-next loop and issue just one order. Only problem is you can only issue one buy order per bar. Whereas the former approach will place multiple orders for the next bar. Usually this will not cause a problem unless your buy/sell levels are very close. The use of the for-next loop is up to one's own programming style. I like the for-next loop.
A For-Loop to Calculate Different Buy/Sell Levels – Turtle Style
Can you figure out what this is doing?
for iCnt = 0 to 3
begin
if lastTradeLoser then
begin
if mp <> -1 and currentContracts = iCnt * lotSize then
begin
buyPrice = hh20 + iCnt * N/2;
end;
if mp <> 1 and currentContracts = iCnt * lotSize then
begin
sellPrice = ll20 - iCnt * N/2;
end;
virTmp = 0;
end;
if lastTradeLoser = false then
begin
if mp <> -1 and currentContracts = iCnt * lotSize then
begin
buyPrice = hh55 + iCnt * N/2;
end;
if mp <> 1 and currentContracts = iCnt * lotSize then
begin
sellPrice = ll55 - iCnt * N/2;
end;
virTmp = 0;
end;
end;
Most EasyLanguage code is compatible with MultiCharts
MultiCharts is a very powerful program that can be purchased outright and seems to be very compatible with EasyLanguage. Their software requires a third-party data feed or ASCII data.
Recent Last Trade Was Loser Filter Example
This just happened recently in the bond market. The LastTradeLoser filter prevented the Turtle 20 bar low entry from occurring. As you can see from the prior trade – it was a winner.
