Ok, thanks. Then maybe could you help me with codesnippet of min. 20 seconds and accordingly then the first tick?

Mm ok, what would be the max period without ticks in your opinion? My pairs are eurusd usdchf eurcad on m15

we can't say....    Als de internetverbinding weggevallen is door werkzaamheden heb je ook geen ticks van je forexbroker

so it doesn't matter what pairs you are trading

I think if you code like

iError = GetLastError();
                   if (iError != 0) // retry if error is "busy", otherwise give up
                    {
                     if(iError==ERR_SERVER_BUSY || iError==ERR_TRADE_CONTEXT_BUSY || iError==ERR_BROKER_BUSY || iError==ERR_NO_CONNECTION 
                       || iError == ERR_COMMON_ERROR || iError==ERR_TRADE_TIMEOUT || iError==ERR_INVALID_PRICE || iError==ERR_OFF_QUOTES 
                       || iError==ERR_PRICE_CHANGED || iError==ERR_REQUOTE || iError == ERR_TOO_MANY_REQUESTS) Sleep(RetryTime);

 you can run more ea's. make only 20 seconds delay for chart ea

otherwise make  something like

value int Trades;

if (OrdersTotal() != Trades)
   {
   if(Trades < OrdersTotal())lastOpen = now;
   Trades = OrdersTotal();
   }

 in this part

if(Trades < OrdersTotal())lastOpen = now;

you can make extra condition checking the trades for magicnumber and symbol

Fri 4 pm to Sun 6 pm = 38 Hours (+24 more if Friday or Monday is a Forex Holiday)

Thanks again all. 

@WHRoeder; yes you are right. But personally I don't take positions over the weekend (will turn it off firday afternoon).

@De vries; Thanks for your suggestion!

I put '20' after sleep and then paste the code in my ea? What is the position to paste?

(sorry maar snap niet exact waar ik de code moet inserten en wat ik er nog aan toe moet voegen..)

and if you fail then show your attempt so we can see where you get wrong my crystal ball doesn't show the problem you have

there might be more wrong with your code we don't know

Did you read the manual on Sleep? What does '20' mean?

Dear WHRoeder,

 

Thanks, you helped me a bit further again. So that makes:

 

iError = GetLastError();
                   if (iError != 0) // retry if error is "busy", otherwise give up
                    {
                     if(iError==ERR_SERVER_BUSY || iError==ERR_TRADE_CONTEXT_BUSY || iError==ERR_BROKER_BUSY || iError==ERR_NO_CONNECTION 
                       || iError == ERR_COMMON_ERROR || iError==ERR_TRADE_TIMEOUT || iError==ERR_INVALID_PRICE || iError==ERR_OFF_QUOTES  

                       || iError==ERR_PRICE_CHANGED || iError==ERR_REQUOTE || iError == ERR_TOO_MANY_REQUESTS) Sleep(20000);

It worked out finally. Thanks to all!!

 

What I did:

 

chart 1: no sleep

chart 2: sleep 20000ms (20sec)

chart 3: sleep 40000ms (again 20 sec after 2)

 

and it works fine.

 

If anybody has a nice link with some basic functions I would be gratfull.

Want to optimize a bit with e.g. maxtrades total, mastrades per chart, start hour.

Thing is the rows to make it a setting are easy but I am always doubting where to insert the commands in the code exactly.

 

Basically I am helped..
