Help: When Broker's MT4 runs, but datafeed is blocked

I would need the help of some experienced coder

It happens sometimes that the MT4 of my broker runs, but their price datafeed gets blocked, sometimes for some seconds, sometimes longer up to 2 or 3 minutes, causing problems to my EA, working on very shorts trades in terms of a couple of seconds each.

I guess that it could be a problem in their MT4 / Bridge / Liquidity Provider connection.

I know that the easiest solution to avoid the problem would be to change the Broker, but I would like to ask if anybody knows a way to code any kind of "signal" to my EA when this happens, allowing the EA to suspend any activity until the flow starts regularly again.

Many thanks for your attention and for any possible suggestion.

You don't need to tell the EA to suspend its operations during a shutdown of the data feed ... because an EA works only when there's incoming data.

So it is "off" by itself.

Thanks Ferrux for your reply.

I wish it would be that easy, I wouldn't start this Thread if this was the case.

Anyway thank you.

The ea could "remember" the candletime it opened the last order (or loop through all trades to get that times) and check if the new time is different.
if no new candles are built the candletime/servertime should not change, so this could be the solution ...
PM me with coding requests and I'll probably put you on my ignore list

This was an interesting point, thanks Fxdaytrader.
The only point is that my EA doesn't wait for the next Tick (or candle) for acting...
Sorry if I do not go deeper in explanation, I know it would help, but I would prefer to avoid that now.

Anyway food for thoughts, thanks.
An internal timer could be a way...even if not ticks....

simple scheme, should work:

static int lastordertime=0;

int init() blablup
int deinit() blablup

int start() {

blablup order to send = buy or sell
sendorder(type)

}

void sendorder() {
if (lastordertime!=iTime(Symbol(),0,0)) {
lastordertime=iTime(Symbol(),0,0);
bool result = OrderSend(blablup);
}
}


}

Thank You for your effort, appreciated.

Anyway I cannot rely on the time passed since tha last order time.
Even since the last tick issue could be too late.

I am afraid that the only solution would be the broker to solve the issue internally

They probably have a problem of communication with their liquidity provider.

Thanks anyway

Hi Whenever,

Maybe you could try to set a timer with 'EventSetMillisecondTimer' or 'EventSetTimer' and use it as a counter.

On each new tick you have to reset the counter, then if the counter goes beyond your predefined value, you act on your EA.
Simplicity is the Ultimate Sophistication.
