Vigor:
I will make a manual, but a short one. ...................

And a manual for adding your own functionality (indicators, log elements, states, etc.).

Ideal (but not easy) variant: to make all functional elements "easily attachable", like plugins, so that they multiply and multiply in the codebase like mushrooms ... :)

Cool thing you've done, Igor. Thank you! I've been playing with it all evening.

I haven't really got into the code yet, but I'm planning to do it this weekend. Very curious to understand in detail how some features are implemented.

At a quick look at the code, the impression is very pleasant.

[Igor Volodin]

Blocks are written in an elementary way! If MQL had a mechanism similar to get_declared_classes, class_exists and is_subclass_of, the whole installation of new functionality would be just an enclode/add file of a new class (a descendant of one of the base classes).

//+------------------------------------------------------------------+
class CAlgoBlockLogicOr: public CAlgoBlockLogic {
        public:
        //+------------------------------------------------------------------+ 
        void CAlgoBlockLogicOr() {              
                setLabel("name",12,20,1,"OR");//--uniq, x, y, fontsize, title                
                //--connectors
                CConnectPointer* pointer1 = new CConnectPointer();
                pointer1.connectType = ALGO_BOOL;
                pointer1.connectDirection = ALGO_DIRECTION_IN;
                pointer1.x = 0;
                pointer1.y = 0.11;
                connectPointers.Add(pointer1);
                
                CConnectPointer* pointer2 = new CConnectPointer();
                pointer2.connectType = ALGO_BOOL;
                pointer2.connectDirection = ALGO_DIRECTION_IN;
                pointer2.x = 0;
                pointer2.y = 0.89;
                connectPointers.Add(pointer2);
                
                CConnectPointer* pointer3 = new CConnectPointer();
                pointer3.connectType = ALGO_BOOL;
                pointer3.connectDirection = ALGO_DIRECTION_OUT;
                pointer3.x = 1;
                pointer3.y = 0.5;
                connectPointers.Add(pointer3);
        }
        
        bool operate(CAlgoBlockLogic* s1, CAlgoBlockLogic* s2) {
                bool S1 = s1.process();
                bool S2 = s2.process();
                if ( S2 || S1 ) {  
                        return (true);
                }
                return (false);
        }
        
        //+------------------------------------------------------------------+
};

And if you do code insertion in visual mode, the new block would add itself. Recompiling EA on the fly and picking up new "generated" includes has already been solved. This is how the update of input parameters of blocks for the tester is implemented now.

[t-x-b]

Hello author, do you have any possibility to post a screenshot of the assembled blocks, or a saved file that gave such a picture on the test? It would be a good manual.

[Igor Volodin]

In the description for codebase it is the same scheme of 4 blocks. Only the value 300 in the operation block is ">". The schematic file is in the archive, unzip it to the folder

C:\Documents and Settings\All Users\Application Data\MetaQuotes\Terminal\Common\.

(the path may be different, it is better to search for the fatpanel.dat file and replace it)

[Igor Volodin]

While the new version is being prepared, I will show a run of the same strategy from 2005. Testing mode "every tick". Experiments with trailing stop:

The diagram shows all parameters of the strategy and its principle. No reinvestments. A version with additional blocks will be published soon.

[Arduz]

Restriction on the number of trades will be actual, because it opens trades on each tick with the specified lot and what is good?

[Igor Volodin]

In this way the volume of the position is gained. Constantly refilled portions "by feel" eventually finds a local extremum on bid. And if you limit the opening of no more than 1 position in one direction, then more favourable opening moments are missed and the strategy fails. It is not difficult to add this restriction: +3 blocks for each direction. AND and IS_BUY(or IS_SELL) + NOT

Thanks, I understand the final volume will be unknown, it's bad....

Version 0.2 doesn't want to work. How do I get it to work?

[Igor Volodin]

This problem was in one of the recent builds of the terminal.

https://www.mql5.com/ru/forum/1111/page232

If the terminal is updated to the latest version (where it is fixed), you need to recompile the indicator (in the folder mql5/indicators/fatpanel/ ) and the Expert Advisor (mql5/experts/fatpanel/).
