Please can someone help me with the mql4 code for alternating buy and sell order.that is if buy order hit a stop loss a sell order should be executed and if a sell order hit a stop loss buy order should be executed.
If your request to loop over orders and do action based on type, then the below might help:
// We go through all the open orders
for(int b = OrdersTotal()-1; b>=0; b--)
{
// we select an order
if(OrderSelect(b,SELECT_BY_POS, MODE_TRADES))
{
if(OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUY)
{
// Do something on buy trades
}
}
if(OrderType()==OP_SELL)
{
// Do something on buy trades
}
}
}
}

I want to back test simple EA only BUY with MT4 Simple moving average 20 period
I see a buy signal and up to 3 orders are running
But when the price is below MA20 it does not automatically close the order
Help me to deal with
void OnTick()
{
double sma20 = iMA(Symbol(),PERIOD_H1,20,0,MODE_SMA,PRICE_CLOSE,0);
if(OrdersTotal()<3)
{
if(Low[1]>sma20)
{
bool ticket = OrderSend(Symbol(),OP_BUY,0.01,Ask,3,0,0,NULL,0,0,clrAliceBlue);
}
}
for(int i=0; i<= OrdersTotal(); i++)
{
if(OrderSelect(i,SELECT_BY_POS))
{
if(OrderType()==OP_BUY)
{
if(Close[1] < sma20)
{
bool ticket_close = OrderClose(OrderTicket(),OrderLots(),Ask,3,clrAliceBlue);
}
}
}
}
}
To close order with type OP_BUY, you should use Bid price insted of Ask.
Check why order isn't close by GetLastError(), in your case it should looks like:
bool ticket_close = OrderClose(OrderTicket(),OrderLots(),Bid,3,clrAliceBlue);
if(!ticket_close){
Print("Error closing the order id: ", OrderTicket(), ", Error code: ", GetLastError());
}
I'm creating a Game App in objective-c which is using Google Play Game services for realtime Multiplayer functionality. I follows the documentation at https://developers.google.com/games/services/ios/turnbasedMultiplayer. In my app there are two options Auto match and Invite Match. Auto Match functionality working fine. But Invite match not.
I follow following Code for this
- (int)minPlayersForPlayerPickerLauncher {
return 1;
}
- (int)maxPlayersForPlayerPickerLauncher {
return 2;
}
- (IBAction)inviteFriendsWasPressed:(id)sender
{
// This can be a 2-4 player game
[GPGLauncherController sharedInstance].playerPickerLauncherDelegate = self;
// This assumes your class has been declared a GPGPlayerPickerLauncherDelegate
[[GPGLauncherController sharedInstance] presentPlayerPicker];
}
on click this button Action follow Screen is open
See here
After that when I enter emailId in textfield there is no action perform to search particular user.
Please help me
Thanks
Unfortunately, the player selection no longer works since Google+ is no longer integrated into Play Game Services: https://android-developers.googleblog.com/2016/12/games-authentication-adopting-google.html

As a part of my final year project in university I'm analysing Twitter data using graph entropy. To briefly outline the purposes:
I want to collect all tweet from a certain area (London) containing keywords "cold", "flu" etc. This part is done using Streaming API.
Then I want to access each of the user's (who tweeted about being ill, collected in previous section) list of followers and following to be able to build a graph for further analysis. And here I'm stuck.
I assume for the second part I should be using Search API, but I keep getting error 88 even for a single user.
Below is the code I use for the first part:
final TwitterStream twitterStream = new TwitterStreamFactory(cb.build())
.getInstance();
StatusListener listener = new StatusListener() {
public void onStatus(Status status) {
User user = status.getUser();
long userid = user.getId();
String username = status.getUser().getScreenName();
String content = status.getText();
GeoLocation geolocation = status.getGeoLocation();
Date date = status.getCreatedAt();
if (filterText(content)) {
System.out.println(username+"\t"+userid);
System.out.println(content);
System.out.println(geolocation);
System.out.println(date);
try {
getConnections(userid);
} catch (TwitterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
//OTHER LISTENER METHODS
};
twitterStream.addListener(listener);
// London
double lat3 = 51.23;
double lat4 = 51.72;
double lon3 = -0.56;
double lon4 = 0.25;
double[][] bb = { { lon3, lat3 }, { lon4, lat4 } };
FilterQuery fq = new FilterQuery();
fq.locations(bb);
twitterStream.filter(fq);
private static boolean filterText(String tweet) {
return tweet.contains("flu")
|| tweet.contains("cold")
|| tweet.contains("cough")
|| tweet.contains("virus");
}
And this is what I'm trying to complete the second part with:
private static void getConnections(long id) throws TwitterException {
Twitter twitter = new TwitterFactory().getInstance();
long lCursor = -1;
IDs friendsIDs = twitter.getFriendsIDs(id, lCursor);
System.out.println(twitter.showUser(id).getName());
System.out.println("==========================");
do
{
for (long i : friendsIDs.getIDs())
{
System.out.println("follower ID #" + i);
System.out.println(twitter.showUser(i).getName());
}
}while(friendsIDs.hasNext());
}
Any suggestions?
When you receive error 88, that's Twitter telling you that you're being rate limited:
The request limit for this resource has been reached for the current rate limit window.
The search call is limited to either 180 or 450 calls in a 15 minute period. You can see the rate limits here and this documentation explains the rate limiting in detail.
As for how to get around it, you may have to throttle your search calls to the API. Twitter4J provides ways to inspect current limits/exhaustion which may help - see Twitter#getRateLimitStatus().
I want to play specific points in a Youtube video. Is there a possibility to stop a video on a certain timepoint with the YouTube javascipt API or maybe with another video website as Vimeo?
I can now say (pseudocode)
PlayFragment(start, stop){
player.seekTo(40);
player.stop();
}
But I want to stop at for example point 60, to show only the fragment of 20 seconds.
Is there any possibility for this. Or maybe using onStateChange or another trigger when video is on certain timepoint?
There looks like there is, check out this link for 'YouTube JavaScript API Reference'
https://developers.google.com/youtube/js_api_reference
PlayFragment(start, stop){
player.seekTo(40);
while(player.getCurrentTime() !> 60)
{
sleep(1000);
}
player.stop();
}
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
Typically I'd set an interval, then check "has the timestamp passed 60 since last time? if so, stop"
There's also a "start and end" option you can put in the URL itself which may be useful...
Outlook rules are putting all Facebook originating mail into a Facebook folder, an external process is running as detailed here to separate the contents of that folder in a way that was not feasible through Outlook rules process, originally I had this process running in VBA in outlook but it was a pig choking outlook resources. So I decided to throw it out externally and as I want to improve my c# skill set, this would be a conversion at the same time. Anyway the mail processing is working as it should items are going to correct sub-folders but for some reason the temporary constraint to exit after i number of iterations is not doing as it should. If there are 800 mails in the Facebook folder ( I am a member of many groups) it only runs through 400 iterations, if there are 30 it only processes 15 etc.
I cant for the life of me see why - can anyone put me right?
Thanks

Do not use a foreach loop it you are modifying the number of items in the collection.
Loop from MAPIFolder.Items.Count down to 1.
