Are you sure you run the correct expert.

I just checked and found out that the Max lots are exporting properly to the Expert Advisor.

Please take a look at the Control Panel -> Expert Advisor tab.

There are two option for setting the re-export behavior. If you have the first option set, FSB will override the old version  of the file. The second option lest the FSB creating a new file with a (1) suffix.

Be sure you have the first option on if you want to override your old expert.

Can you reproduce the issue? If you can make screenshot of the FSB settings and the EA settings with the different parameters?

FSB has one algorithm for exporting Expert Advisor. It is not possible the first time to export it correctly, but the second time to export it wrong.

I'm 100 sure that the problem is that MT doesn't recover the EA settings correctly. I've read in the http://www.stevehopwoodforex.com/phpBB3/index.php forum that we have to never rely on that.

I can help you only if you reproduce a bug in FSB and post the exact steps for reproducing, the expert and the screenshots of all settings.

You should never refresh a working EA especially on a live account. The EA has tens of parameters in the MT memory out of the input parameters. MT will not recover them.

I change my experts only at a moment when there is no open positions. I do it by removing the EA from the chart and attaching it again and preferably on Saturday or on Sunday when the market is closed. And only if the FSB backtester doesn't show an open position at that time.

Yesterday I lost 1 hour trying to make the new version of the bridge running without success. Finally I restarted MT and it appeared that the bridge is working flawlessly. 

However, I must say that the latest versions of the MQL language are much better than before. I almost decided making a self-generating, optimizing and trading expert !!!

Hi Popov,

Can you consider changing the maximum lot default to "0" instead of "20" so that if in any case because of bug issue, the EA would not end up adding 20 lots.

Hi Popov,

Yes, I realised can't be "0" but at least "1" or do an auto calculation based on (i.e. this amount will change according to) the in put for A) "Entry amount for a new position and B)"additional entry signal"

Eg 1.  If Entry amount for new position is "1" and no "additional entry signal" is chosen, then the maximum amount is "1"

Eg 2. If Entry amount for new position is "1" and "additional entry signal", "winner" and "amount to add on position" is "1", then the maximum amount is "1+1=2 or manual input to 4"

Although you said that there isn't any default for maximum position allowed.  When I open a new strategy in the FSB Pro, the maximum position amount is set at "20" already.

And when I open the EA properties in the MT4, the maximum position allowed is set at "20" too (this is fine when the "additional same direction signal" is set as "nothing", the EA will follow the amount set by "Entry amount for a new position". 

However, in the event of bug issue such as my case, whereby I choose "additional entry signal" as winner and "amount to add position" is 1 and the maximum is 4.  And because of the bug issue, the MT4 take into account the instruction to add position but didn't update the "4" lots as maximum but remain in the default "20" and hence, add 20 positions instead of 4.  Hence, I thought for safety issue, can you either consider to change the "default" setting 20 to something else be it 1 or auto calculation? or allow the user to change this setting manually (as in the current case, the only difference is that "20" is not the preset number)

I rather the preset maximum number be set at 1 than 20 and then let the user adjust accordingly.  Because in event of a bug issue, 20 lots opened unintentionally is a disaster.  I hope you understand what I'm driving at.  You always looked into safety issue.  And I think it is good to prevent my case from repeating again although, it is no fault of FSB Pro but as you mentioned the bug lies with the MT4.  But for user protection, it's good to look into how to minimize the potential danger if bug issue arise again.

That's weird, because when I click on "New Strategy" tab in the FSB Pro, under the "Maximum position amount" [lot], the preset value is "20".

The screenshot is from FSB. It has default value 20 for Max Lots.

The expert code is here: PopovMP/FSB_Expert_Advisor_Code. It doesn't have Max Value settings.

The only way the number 20 to appear to the EA is to be exported from FSB. During the export the program replaces the string 77702 with the real settings.

// -----------------------    External variables   ----------------------- //

extern double Entry_Amount    = 77701; // Amount for a new position #TRADEUNIT#
extern double Maximum_Amount  = 77702; // Maximum position amount [lot]
extern double Adding_Amount   = 77703; // Amount to add on addition #TRADEUNIT#
extern double Reducing_Amount = 77704; // Amount to close on reduction #TRADEUNIT#

See: https://github.com/PopovMP/FSB_Expert_A … rt_MT4.mq4

THE ONLY WAY TO SEE 20 IN THE EA IS TO EXPORT IT FROM FSB.

Your EA cannot fabricate this number alone.

There is very easy solution to you request. Simply set what ever default settings you need and save a Template. Later, when you need a new strategy, open the saved template.
