mql - How to enter a new order only if / when the first one has been executed (filled)? [MQL5] -


i'm kinda of new in mql5.

i have ea buys 1 stock first (let's petr4) , buys 1 (let's abev3).

the problem can order second 1 when first 1 executed (not placed).

i used mqltraderesult.retcode return number, shows if order has been placed , need know if order has been filled in order continue second operation.

can me? thanks

such indication ought coded in positionselect() call:

first call
if ( positionselect( "petr4" ) ) { ... /* further work go here */}

this chooses open position further working it. returns true if function completed. returns false in case of failure.

if there active position reported given symbol, further work go ahead inside {...}-code-block

the hidden magic in fact, there either single-position symbol, or none @ all. makes rest of logic crystal-clear.

execution of trade operations results in opening of position, changing of volume and/or direction, or disappearance. trade operations conducted based on orders, sent ordersend() function in form of trade requests. each financial security (symbol) 1 open position possible. position has set of properties available reading positionget...() functions.
...
position_ticket
unique number assigned each newly opened position. matches ticket of order used open position except when ticket changed result of service operations on server, example, when charging swaps position re-opening. find order used open position, apply position_identifier property.

position_ticket value corresponds mqltraderequest::position.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
