Hey,

The DrawRectangle code block does not generate MQ code for successful completion of function and to continue program flow.

Can take a look at the gif I uploaded. Code gen for Start4 does not include a call to Start5.

Thanks.

Rectangle Code Block Problem.gif

Hey,

I'm finding that I need to expand the functionality of my FxDreema EA's by using Static Variables to manage market / indicator events and conditions at the time they happen, and then later act on these events during other market conditions, without having to loop back through indicator array buffers to see if other indicator events happened in the recent past.

So, if I could use Static Variable, as they are defined for MQ4... permanent memory and don't get re-initialized when an EA function exits.... http://docs.mql4.com/basis/variables/static

Simple example.

. Current Price Bar causes the MACD to cross above zero.
(however.. the EA system must have confirmation from the CCI indicator & 3 Price Bars with higher lows before going Long the EURUSD)

So..
..... at some point later in the day..... the CCI reads greater than 50, confirming market is trending Up
..... and at some other point later in the day..... the market provides 3 Price Bars with higher lows, once again confirming market is trending Up

Now..., at this point the EA must loop back in time (indicator array buffers) to determine if the CCI > 50 and MACD > 0, and if so, open a Long position now on the current price bar....

I can see taking 1 of 4 approaches to code this....

1. Use 2 MQ4 Static variables, one for MACD and another for CCI. As the market prices pass through the EA, I would use the static variables to boolean (TRUE/FALSE), when the indicators confirmed an up trend, in the context of prices movements in time (ie. during up/down trends, 3 higher lows, 3 lower highs, etc)
   -or-
2. Loop thru the indicator buffers, at the time when the 3 Price Bars with higher lows occurred.
   (This is currently awkward using the fxdreema "LOOP" blocks, and result in many other custom blocks just to loop an indicator array buffer, clutters the drawing canvas with too many blocks, error prone, tedious, etc.....)
   -or-
3. Hand code a custom MQ4 indicator that would combine MACD & CCI & the Last 3 Price Bars to output a separate indicator array buffer that would show 1/0 for yes/no to open a long position based on MACD Xover 0, CCI>50, Low(1)>Low(2)>Low(3). Upload the indicator to FXDreema, setup the code blocks, etc. (not optimal, I don't want to have to create a custom indicator for every type of trading rule that I need in an EA)
   -or-
4. Hand code all Static variables and handling logic in Library Studio. (I could define the static variables in a custom block in library studio. But I can't access the variables outside of the custom library studio code block, so all code logic to use the static variables would have to be placed in the custom library code block. This would be tedious, defeats the purpose of using FxDreema, slows down my development, error prone, etc)

So.. Approach #1 is what I would prefer.....and would be the most efficient, agile, and easiest to code and maintain, now and in the future....

Do you have plans to introduce Static variables into the FxDreema interface build of EA's, or am I missing something here.....

Please let me know...

Thanks

I've exported the xml to the desktop version and regenerated the MQL code.

It compiles fine now using the Desktop version of FxDreema to generate the code.

However, can you pls look at fixing the internet version.

Thanks

I'm getting the following compilation errors:

'?' - expression on global scope not allowed
'?' - variable not defined

The code has "?>" characters on a single line right after routine "int PipValue(.."
The code was generated by the internet version of FxDreema.

MQ4 Code Gen Error on Compile.GIF

When I click back in Actions History, the canvas remains blank.

I'll enter the chat room and wait for you.

I also agree. I use it everyday... all the time.

I welcome the desktop version. In addition to the many productivity benefits I already enjoy using the FxDreema platform, the desktop version also eliminates the possibilities of internet network outages and latency, leverages the full potential of my local PC, and is nicely integrated with MetaTrader.

Excellent work.

I'm getting an error while trying to Copy / Paste code blocks using the desktop version. Here is how it happens.

1. Drag-Select code block
2. Right-click of code block and select "copy"
3. Right-click on canvas and select "paste"
4. FxDreema message "Blocks copied successfully" but canvas redraws with no code blocks... Canvas is now blank.

....

If I click "Reset", the canvas redraws, but my copied/pasted block is not there. (like an undo function).

If instead of clicking "Reset", I click "Save" - FxDreema message reads "Data mismatch, Reload in 3 seconds..."

After waiting 3 seconds, the canvas redraws successfully with the copied/pasted block.

Thanks.

Yep. I got it. It's working.

My mistake was as you said, I left-clicked on the canvas first, which caused the block I was copying to unselect or not be yellow anymore.

Thanks...

Yep. Thanks great, I got it. I'm able to copy the block.

What and/or where do I have to click to paste it.
I tried using FireFox edit menu, but paste is dimmed.

I think this would be extremely useful and really boost productivity and ease-of-use.

It would be great if I could select a block, right-click and have the option to "Copy", and then right-click on the EA canvas and have the option to "Paste".... as an example.

Or

Implementing "copy & paste" as buttons under the "libraries and candlestick patterns" on the left side of the EA canvas.

Thanks

I think it would be useful.

It would really help in organizing the coding space of the browser.

Now I segment my code for those code blocks I execute for each tick on the right side, and those for each bar on the left side.

I further segment code blocks from the top down separated by 'empty blocks' by event.

If FxDreema had selectable event tabs next to "init, deinit, start", I could improve the structure of my coding logic.

That's great! I'm glad to hear that it's on the way. Thanks. I'm looking forward to it.

Hey,

Please implement a "Save as..." under the "Experts" dropdown menu.

It would be very useful when making versions of an EA, while adding/changing trading strategies, and testing performance.

Currently, when need to make a new EA version, I have to re-click / re-input my EA from scratch, block for block, manually. It’s a pain.

What you think....
