Hello,
I am relatively new to Tradestation and would need some help from expierenced TS programmers in understanding below attached Turtle strategy.
I am hoping that there are some members which can help me to fully understand below code.
Below is the first part of mentioned Turtle strategy attached, including my comments as I think the instrcutions will be executed, on some statements I simply have no clue what they are really doing, hopefully some members can explain them in detail.
Currently I donīt think it makes sense to post the entire strategy, so I will go ahead and post below the first part
In BLUE are my comments, as I said, would be great if somebody can tell me if my analysis of below code is correct and on sections where I simply donīt know whats going on if possible please provide some further assistance.
Thanks a lot to everbody!
Below are the first 30% of given TS code:
[LegacyColorValue = true];
{ Turtle mode #2 Ver.0.1.0 03.02.2005}
Input: DistH(4),DistL(4),Account(10000),MaxPercRisk(1),MaxOpenEntry(4);
Var:TradeAccount(-1),PosSize(0),TrailBars(10),CurrentPosition(0),cCurrentEntries(0),
cAvgEntryPrice(0),cEntryPrice(0),cCurrentContracts(0);
Var:BuyStop(-1),BuyLimit(-1),LExitStop(-1),SellStop(-1),SellLimit(-1),SExitStop(-1);
Var:NextHigh(-1),NextLow(-1),BarUntil(-1);
Var:BreakType(0),BreakStop(-1),BreakBars(0),BreakIsLoss(false),Break20Found(false),Break20SkipCnt(0);
if Barnumber=1 then begin {Start with 1 bar on chart}
VALUE29=-1; {Numeric value set to -1, for later usage, currently donīt know the meaning of -1}
VALUE38=-1; {Numeric value set to -1, for later usage, currently donīt know the meaning of -1}
end;
cCurrentEntries=CurrentEntries;
{"CurrentEntries" -->numbers of entries currentlyopen, assigned to"cCurrentEntires"}
cAvgEntryPrice=AvgEntryPrice;
{AvgEntryPrice --> Average price of all currently open entries --> assigned to "cAvgEntryPrice"}
cCurrentContracts=CurrentContracts;
{CurrentContracts --> Number of contracts currently open --> assigned to "cCurrentContracts"}
if (cCurrentEntries>cCurrentEntries[1]) then begin
{(cCurrentEntries>cCurrentEntries[1]) --> if "cCurrentEntries" is bigger that the one from yesterday, but so far there are no trades made, value for both is still 0, condition not met, jump to next "if" --> if (cCurrentEntries=0 and cCurrentEntries[1]<>0) then begin}
cEntryPrice=(CurrentContracts*AvgEntryPrice-cCurrentContracts[1]*cAvgEntryPrice[1]) / (CurrentContracts-cCurrentContracts[1]);
{Calculation for var "cEntryprice" --> (Number of currently held contracts * average price of all currently open entries) - ( values from yesterday) / (currently held contract - the ones from yesterday)}
--> same thing: currently no trades in progress, all vars still set to 0
--> What does "cEntryPrice" basically say? actually donīt understand the meaning of this calculation.
if MarketPosition=1 then begin
{ if long than continue --> condition not met, no trades in progress}
LExitStop=TicksRound(cEntryPrice-2*XAverage(TrueRange,20));
{ I guess thatīs the "2N" initial stop calculation according to Turtle rules}
NextHigh=cEntryPrice+0.5*XAverage(TrueRange,20);
{no idea...., whats the meaning of this "NextHigh"?}
NextHigh=TicksRound(NextHigh+TicksMTS(NextHigh));
{no idea...., whats the meaning of this "NextHigh"?}
BuyStop=-1;
{predefined vars, as above. Whatīs the reason to have them all on -1?)
BuyLimit=-1;
{predefined vars, as above)
BarUntil=-1;
{predefined vars, as above)
VALUE29=-1;
{predefined vars, as above)
end
else begin
SExitStop=TicksRound(cEntryPrice+2*XAverage(TrueRange,20)); {same as above, just SExit)
NextLow=cEntryPrice-0.5*XAverage(TrueRange,20); {no idea...., whats the meaning of this?}
NextLow=TicksRound(NextLow-TicksMTS(NextLow)); {no idea...., whats the meaning of this?}
SellStop=-1;
{predefined vars, as above. Whatīs the reason to have them all on -1?)
SellLimit=-1; {predefined vars, as above)
BarUntil=-1; {predefined vars, as above)
VALUE38=-1; {predefined vars, as above)
end;
{ Date & Time line for multiple entries Buy / Sell }
value99=date; {predefined numeric values --> date}
value98=time; {predefined numeric value --> time}
end;
if (cCurrentEntries=0 and cCurrentEntries[1]<>0) then begin
{cCurrentEntries is 0, but cCurrentEnties from yesterday is equal to 0 --> condition not met to proceed, so far no trades made}
NextHigh=-1;
NextLow=-1;
LExitStop=-1;
SExitStop=-1;
BuyStop=-1;
BuyLimit=-1;
SellStop=-1;
SellLimit=-1;
BarUntil=-1;
if VALUE29>=0 then {so far value29 is still set to 0, cannot proceed}
TL_Delete(VALUE29); {delete trendline}
VALUE29=-1;
{in case value29 changed --> now re-setting "value29" to -1}
if VALUE38>=0 then {so far value38 is still set to 0, cannot proceed}
TL_Delete(VALUE38); {delete trendline}
VALUE38=-1; {in case value38 changed --> now re-setting "value38" to -1}
end;
