I have a problem when I'm trying to find a way to check if a trade was made on the current bar or not to stop the EA for making multiple entries on the same bar.
When I don't do a multi Currency EA I usually just use
static datetime lastTradeBar;
and
if(lastTradeBar!=Time[0])
{
if(PFTP_BuySignal > 0 && PFTP_BuySignal_Prev == 0 && PFTP_Rate > PFTP_Rate_Value)
{
myTP = PFTP_TP1;
mySL = PFTP_BuySL;
return (1);
}
if(PFTP_SellSignal > 0 && PFTP_SellSignal_Prev == 0 && PFTP_Rate > PFTP_Rate_Value)
{
myTP = PFTP_TP1;
mySL = PFTP_SellSL;
return (-1);
}
else
return (0);
lastTradeBar=Time[0];
};
return (0);
}
but this doesn't work when using it as I do now.
I'm thinking I need to make a myArray[sym,period,lastTradeBar] or myArray [sym][period][lastTradeBar]
but I can't wrap my head around how or where to put it.
this is the flow
int OnInit() ->
void OnTimer() ->
void LoopThruSym(stringlistOfSym) ->
void LoopThruPeriod(string sym, string listOfPeriods, int listOfSym) ->
void Trade(string sym, int period) ->
int Signal(string sym, int period)
This is how the flow is now.
int OnInit()
{
EventSetTimer(5);
return(INIT_SUCCEEDED);
}

void OnTimer()
{

Code a function on the "void OnTick()" like this:
void OnTick()
{
//---
CheckForSignal();
}
And then code the function "CheckForSignal()"
//+------------------------------------------------------------------+
//| Function "CheckForSignal()" |
//+------------------------------------------------------------------+
void CheckForSignal(){
//check here a bar until a Signal given Signal given then initialize it to Time[]
static datetime candletime=0;
if(candletime!=Time[0]){
double upArrow=iCustom(your Custom indicator or whatever parameters);
if(upArrow != EMPTY_VALUE){
EnterTrade(OP_BUY);
}
double downArrow=iCustom(your Custom indicator or whatever parameters);
if(downArrow != EMPTY_VALUE){
EnterTrade(OP_SELL);
}
// if we have a Signal we will initialize candle time to Time[0] to avoid multiple Orders
candletime=Time[0];
}
}
//+------------------------------------------------------------------+
Then Send Signal to Open or Close or whatever you need in my example we will open Trades
//+------------------------------------------------------------------+
//| Function "EnterTrade()" |
//+------------------------------------------------------------------+
void EnterTrade(int type){
int err=0;
double price=0;
double sl=0;
double tp=0;
if(type == OP_BUY){
price=Ask;
}else{
price=Bid;
}
//steppoin8-step15: replace function "OrderSend" parameter
// ->variablename "name" (magic)
//steppoint8-step16: end ";"
int ticket=OrderSend(Symbol(),type,LotSize,price,slippage,0,0,"EA Trade",magic,0,clrMagenta);
if(ticket>0){
if(OrderSelect(ticket,SELECT_BY_TICKET)){
if(OrderType()==OP_BUY){
sl=OrderOpenPrice()-(stopLoss*pips);
tp=OrderOpenPrice()+(takeProfit*pips);
}else if(OrderType()==OP_SELL){

This is not an answer more of like progress.
So what i'm doing not instead of checking for candletime=Time[0] I check then the last trade close time is for that sym/magic nr and comment. and then runing it thru if(iBarShift(sym,period,OrderCloseTime()) > 1)
this kinda works but I'm getting problems down the road if I'm trying to use symbols with different miniLots. But that will come on another post.
bool getLastOrderClose(string sym, int period)
{
if(OrdersHistoryTotal() == 0)
return true;
string comment = "Multi Currency "+sym+":"+IntegerToString(period);
int count = 0;
int tradesPerSymbole =0;
for(int i=OrdersHistoryTotal()-1; i >= 0; i--)
if(OrderSelect(i, SELECT_BY_POS, MODE_HISTORY))
{
if(OrderSymbol() == sym)
{
if(OrderMagicNumber() == Magic)
{
tradesPerSymbole++;
if(StringFind(comment,OrderComment())<0)
{
if(iBarShift(sym,period,OrderCloseTime()) > 1)
{
return true;
}
}
}
}
}
else
{
Print(sym +" : "+"OrderSend() - getLastOrderClose - error - ", ErrorDescription(GetLastError()));
}
if(tradesPerSymbole == 0)
return true;
return false;
};
//OrderSend('EURUSD',blablabla Parameter)
//OrderSend('GBPUSD',blablabla Parameter)
//OrderSend('USDJPY',blablabla Parameter)
//OrderSend('EURCHF',blablabla Parameter)
int ticket=OrderSend('EURUSD',type,LotSize,price,slippage,0,0,"EA Trade",magic,0,clrMagenta);
for(int I=ticket;ticket<Orderstotal();i++){
if(OrderSelect(ticket,SELECT_BY_TICKET)){
if(OrderType()==OP_BUY){
sl=OrderOpenPrice()-(stopLoss*pips);
tp=OrderOpenPrice()+(takeProfit*pips);
}else if(OrderType()==OP_SELL){
sl= OrderOpenPrice()+(stopLoss*pips);
tp= OrderOpenPrice()-(takeProfit*pips);
}
if(!OrderModify(ticket,price,sl,tp,0,clrMagenta)){
err=GetLastError();
Print("Encountered an error during modification!"+(string)err+" "+ErrorDescription(err));

I think its not the pro solution but I would declare a Ordersend function for all the pairs where u want to open the order (I need not to say that the order send function should be declared in a conditional so only the the real ordersend be placed)
but the part where I want your attention is you can do it the hardware by declaring the Ordersend(not with Symbol() instead of that with "YourPairname");
hope this help you a little bit to reach your goal gl
I have some entries in my app which contain some numbers and I have a button that when I click on the button it adds one unit to the number in the entry that is focused, but the problem is that when i click the button, the entry loses the focus and keyboard disappears, although I want the entry to be focused, I found a solution for Android, but couldn't find anything for iOS!!
Does anybody know what to do? I don't want the entry to lose focus
Update:
private void StepUpButton_Clicked(object sender, EventArgs e)
{
double value;
for (int i = 0; i < 30; i++)
{
if (GetEntries(i).IsFocused)
{
if (String.IsNullOrEmpty(GetEntries(i).Text) || GetEntries(i).Text.Equals("-"))
{
value = 0.00;
}
else
{
value = Convert.ToDouble(GetEntries(i).Text);
}
for (int j = 0; j < 10; j++)
{
if (GetEntries(i) == GetVa1ToVb1Amp(j))
{
GetVa1ToVb1Amp(j).Text = controller.StepUpClicked(0, value).ToString("F2");
}
if (GetEntries(i) == GetIa1ToIb3Amp(j))
{
GetIa1ToIb3Amp(j).Text = controller.StepUpClicked(1, value).ToString("F3");
}
if (GetEntries(i) == GetVa1ToIb3Phase(j))
{
GetVa1ToIb3Phase(j).Text = controller.StepUpClicked(2, value).ToString("F2");
}
if (GetEntries(i) == GetVa1ToIb3Freq(j))
{
GetVa1ToIb3Freq(j).Text = controller.StepUpClicked(3, value).ToString("F3");
}
}
}
}

I'm trying to build a game in iOS and am currently using Objective-C. The problem I'm running into is Z-sorting different enemy and player nodes. This is my current code for Z-sorting just one enemy type, and I am only copying this code to z-sort every different type of enemy (Mob). This is leading to ALOT of code that all does essentially the same thing for different objects. The only way I know how to fix this problem is by using template functions, but Objective-C doesn't support that to my knowledge. There has to be a better way...
// If two monsters are standing on the same cell, we need to z sort them based on position
// south-western most body will be closest to the "camera" from players perspective
-(void) zSortMobs {
int i = 0;
int j = 0;
for (i = 0; i < self.maxMobs; i++) {
Mob * mob = [self.mobs objectAtIndex: i];
if (mob.state != 0) {
for (j = 0; j < self.maxMobs; j++) {
Mob * mob2 = [self.mobs objectAtIndex: j];
if (mob2.state != 0) {
if (mob != mob2) {
if (mob.z == mob2.z) {
if (mob.y < mob2.y) {
mob.z++;
}
else if (mob.y == mob2.y) {
if (mob.x < mob2.x) {
mob.z++;
}
else {
mob2.z++;
}
}
else {
mob2.z++;
}
}
}
[mob setZPosition: mob.z];
[mob2 setZPosition: mob2.z];
}
}
for (j = 0; j < self.maxTanks; j++) {
Tank * tank = [self.tanks objectAtIndex: j];
if (tank.state != 0) {
if (mob.z == tank.z) {
if (mob.y < tank.y) {
mob.z++;
}
else if (mob.y == tank.y) {
if (mob.x < tank.x) {
mob.z++;
}
else {
tank.z++;
}
}
else {
tank.z++;
}
}
[mob setZPosition: mob.z];
[tank setZPosition: tank.z];
}
}
if (mob.z == self.gameScene.player.z) {
if (mob.y < self.gameScene.player.y) {
mob.z++;
}
else if (mob.y == self.gameScene.player.y) {

mob.z++;

What do you mean by "shooting" ?
So you have your tuioClient and you initialize it in setup(). Thats good, because then the callback methods (addTuioObject, removeTuioObject, updateTuioObject, addTuioCursor, updateTuioCursor, removeTuioCursor, refresh) will fire whenever your sketch receives a TUIO message.
Keep in mind that TUIO is based on OSC which is transported over UDP. That means the tracker (reactivision & co) will have to send to the IP and port your sketch is listening to. If both are on the same machine use 127.0.0.1 and port 3333 (default).
Have a look at the examples. You'll find them in the processing "IDE" click:
"File -> Examples"
and Navigate to
"Contributed Libraries -> TUIO"
