I noticed the same thing too with video_set! Emre, to me this is very elegant and simpler code, thank you.

It currently works without hitch/error on my desktop, so I'm going to be testing it on my laptop and post the results here today.

Thank you JCL, for your reply.

Please pay attention that there is ONE global parameter, so if I use your suggestion - no parameters train would take place.

Code
function run()
{

	set(PARAMETERS|LOGFILE);
	BarPeriod    = 1440;
	StartDate    = 2010;
	LookBack     = 1000;
	Verbose      = 7;
	assetList("AssetsZ9.csv");

	asset("AGG");
	int Max_Long_Assets = optimize(2,1,4,1);
//	int Max_Long_Assets = 2;

	
	while(asset(loop(Assets))) {
		vars Prices     = series(price());
		var  sma5       = ROC(Prices,5);
		
		var signal1     = SMA(Prices,5);
		var signal2     = SMA(Prices,30);
		var Threshold1  = optimize(0.05,0.0,0.1,0.01);
		var Threshold2  = optimize(0.05,0.0,0.1,0.01);
		int RR  = signal1 - signal2 <  Threshold1;
		int TT  = signal1 - signal2 >= Threshold2;
//		printf("\n%.3f %.3f",sma5,signal1 - signal2);
		
		
		int In = (sma5<0 && RR==1) || (sma5>0 && TT==1);
		int Out= (sma5>0 && RR==1) || (sma5<0 && TT==1);
		
		int NewShares = Balance/priceClose(0)/Max_Long_Assets-LotsPool;
		
		if(In && NumLongTotal < Max_Long_Assets)
			enterLong(NewShares);
		else if (Out)
			exitLong();
//	plot("TT",signal1 - signal2,NEW|LINE,RED);
	}
	
}



Zorro's train run results:

Code

XLV history up to date
XLV 3967 ticks read
Loop[8] p1 step  1:  0.00 => 0.00   0/ 0

Loop[8] p2 step  1:  0.00 => 0.00   0/ 0

XLV: 0.050 0.050=> 0.000

Parameters stored in David.par




If I disable the global parameter, then the train works OK

Code

//	int Max_Long_Assets = optimize(2,1,4,1);
	int Max_Long_Assets = 2;  // No global parameter



Code
Loop[8] p2 step  7:  0.06 => 0.72  460/651
Loop[8] p2 step  8:  0.07 => 0.72  461/649
Loop[8] p2 step  9:  0.08 => 0.72  459/649
Loop[8] p2 step 10:  0.09 => 0.73  460/646
Loop[8] p2 step 11:  0.10 => 0.73  458/645
Selected p2[9] = 0.080  => 0.73

XLV: 0.070 0.080=> 0.723

Parameters stored in David.par



The only way I succeeded to optimize ONE global and TWO local parameters , is using "listed_assets", but it works for 7 assets only.

In that case, yes. But the error handler is not so intelligent to make a difference in which situation continuing makes sense and in which not. A failed file access is normally a hard and fatal error and leads to stopping the system. If the system would continue trading with an unread file, the result can be much worse.

Hi Emre, thanks for linking your solution. Here is what I've done so far, with advice and code snippets from both of you.

It currently isnt working 100%, but here is the major parts of the code that I believe help a lot, I think it completely got rid of the 3d Hardware Reset failure crash when waking up from a screensaver:

Code
#include <windows.h>  //----------include windows.h

...

function main()
{

var render_chain_destroy=0;
var render_chain_state=0;

while(1) ///--------------------put this in your main loop
{

BOOL bSaver;  //--------------------------------creates a BOOL flag that will be changed by the windows.h function SystemParametersInfo
SystemParametersInfo(114,0,&bSaver,0);  //---------114 is a specific parameter that tells gamestudio whether or not a screensaver is running

...


        //---------If bSaver is 1/true then it means the windows screensaver is running:

	if((bSaver)||(window_focus==0))  //-----------bSaver is a flag set by SystemParametersInfo above. I put window_focus in here as well 
	{

   render_chain_destroy=1;  //-------get ready to destroy the render chain

        }

       else
      {

      render_chain_destroy=0;  //-------if the screen saver isnt running, dont destroy the render chain

      }



if(render_chain_destroy==1)  //-----we are ready to destroy the render chain because the screensaver is on
{

if(render_chain_state==0)
{

destroy_render_chain();  //-------put your render chain destruction here (remove stages, remove bmaps, purge bmaps
render_chain_state=1;  //-----destroy the chain once
}


}


if(render_chain_destroy==0)  //-------if the system doesnt have a screensaver running
{

if(render_chain_state==1) //------and we recently destroyed the render chain because we destroyed it when a screensaver came on before
{
recreate_render_chain(); //--------recreate your render chain here
wait(-2); //------------I waited 2 seconds here, not sure if this helps or not
render_chain_state=0;  //-------we reset this var to 0, which is only set to 1 when a screensaver is on.

}


}


There some caveats to the above screensaver code. It only consistently works if gamestudio is running in a window. Obviously, if gamestudio is full screen, the screensaver will never trigger.

But lets work on the next hurdle. Locking your computer.

...
if (DeskHwnd != 0)
{
DesktopResult = SwitchDesktop(DeskHwnd);
}


if((DesktopResult==0)||(key_o))
{
...

With Emre's code, I can get gamestudio to recognize when the computer is locked! I destroy the render chain and remove the stages the moment gamestudio detects a lock.

However, when you log back in to a running windowed gamestudio exe, the game gave me a "cant create texture unnamed", but it didnt crash the game. When you select OK, the game seems to run ok in windowed mode after.

If you run the game in fullscreen, then lock, destroy the render chain in gamestudio, then log back in, the game looks like its frozen, however if you press alt+enter, the game seems to unfreeze and start working again.

Emre, have you tried to see if your game works when you run fullscreen, then lock, then log back into the desktop to see what a running gamestudio does?

Thank you two for your help so far.

Hi Preypacer,

I started with the motor in the A5 version and I have to say that it is simply great for people who mainly want to be programmers.
But that is also the problem at the same time. You have to grasp the programming code, i.e. master a programming language.

You mustn't compare this engine to Unreal or Unity.. These primarily rely on visual design, but 3d Gamestudio is primarily a script / code-based design engine.
for one it's an advantage, for the other it's a disadvantage. Of course you have to be able to program in Unreal or Unity in the end to design games, but the connection between the GUI and the Motor Code is more directly linked.

At 3d Gamestudio you only have the blank SED editor at first. If you don't know what you have to or want to do here, it is of course difficult to develop a game with it. As @Dooley wrote, the approach is simply totally different and very directly.

So here is the first question to ask yourself. what do you like are you the coder or the designer.
If you are more of a designer and want to work visually, 3d Gamestudio is not for you and you should look for a different engine.
But if you are a real scripting pure code writer, then 3D Gemstudio is for you :-D

3D Gamestudio is a software package collection. The 3dGS tools like WED, GED and MED unfortunately only support programs. In Fahl von MED, any other modern 3D modeling tool is better, but you will need it to convert models to MDL format as 3dGS cannot work directly with FBX or other models. In theory, you don't need a single tool from 3dGS to program a game, just acknex.exe (Engine) itself.

If 3d Gamestudio can directly use FBX models in the A9 version (hopefully the upcoming version), this will in my opinion be enough to actively play in the Motor League of the greats again.

@Preypacer
If you are still interested in 3dGS you can ask any of us about help and I think everyone will be happy to help.
Search also in YouTube for 3D Gamestudio or 3dGS and you will surely find something useful in English.

If you haven't worked with 3d Gamestudio at all, take a look at my youtube channel here:
https://www.youtube.com/watch?v=BlqktPOyGp8&list=PLZUR_qMkRMVhhV2R_mpImi_vMhw1Dsqo5
It's only in German, unfortunately, but you can use YouTube's automatic subtitle translation to understand at least a little what I'm saying.
My Videos are for total 3dGS beginners and therefore slow enough to be able to understand them all without knowing the German language :-)

I myself am unfortunately not the mega programmer and also not the 3dGS freak, but that is simply because I have too little time for it.

I apologize for my English because I don't speak the language very well

That's already possible on the Zorro side, but AFAIK not yet supported by plugins.

In stead of 2 simultaneous FOK orders, send 2 AON+GTC orders, wait some predefined time, then check the fill with BrokerTrade and send a DO_CANCEL command when not filled.

This requires from the plugin support of GTC, DO_CANCEL, and BrokerTrade.

The printed above was for closing price, tried to use priceClose() which shows the same as default on log and compare to the close price of each candle on TWS chart on same one min timeframe.

I found out the pricetype default on IB was bid/ask how do I enforce to use the Last? to match with the IB TWS

You can use any flag in 3 ways: right way, wrong way, and the Dada way.

The difference between the last two is that when it's the wrong way, one can at least see the intention.

Hi Team:
I am having difficulty in live testing with intrabar trades. In testing with historical Tick data, I obtain intrabar trades within the hourly bar. In live trading, the trades are only sent at the beggining of each bar i.e. every hour.

I use History = ".t1" and the TICKS flag is set already. I also changed TickTime from the default values but that made no difference in live trading. Without going so far as changing TimeFrame to 0 every time an intrabar trade is intended, is there any thing I might be missing?

I have tried changing all orders to Limit Orders by using OrderLimit and even extending OrderDuration to high values.

Just looking for pointers. If you can point me in the direction of any setting I might want to try.

Thanks
Optimus

Use enterTrade(). This feature was added to Zorro after I made this request.

Another comparable new feature is the brokerCommand GET_TRADES. It deletes all of your Zorro-side trades and replaces them all with detected trades on the broker plugin. Obviously, your broker plugin must support this feature.

Maybe in better words, traincycle 1 without stoploss finds from 20 parameters 15 profitable, traincycle 2 should be possible to train the SL only for the previously found profitable ones (and omit the the 5 unprofitbale ones, to prevent making them profitable by SL only).

For cancelling the remainder of an unfilled order, select the trade and set TradeLots = TradeLotsTarget-TradeLots, then exit the trade. This should work at least in theory.

This can happen when the lookback period ends with an incomplete bar. The bars are no duplicates, they have different prices and if you would suppress one of them, the series weren't 100% correct either. But you can use the NOSHIFT flag of the current beta version for this.
