Do brokers set a max open trades limit?

I have a busy EA. I want to have MANY more than 200 trades open at one time.

Using FXDD, I notice trading stops at 200 trades. Is this an MT4 thing? Or is it a broker thing?

Every broker has max lot size for a single trade. In your case is 200.
If you want more you have to open more trades. for instance, 400 lots = 2 trades x 200 lots.

Usually max. opened positions at the same time limitation is set by broker.

As long as you have the required margin you can open as many lots as you wish. Limits are for a single trade, not for a total open lots

Volume - yes.

But the threadstarter asked (correct me if I'm wrong) about the number of opened trades (regardless of their volume(s)). And this number is usually limited.

Thanks guys.

Yes I have confirmed with various brokers that many do set a limit to the number of maximum open-at-one-time trades.

FXDD for example have a 200 trades open limit.

GoMarketAus do not have a limit to open trades - but they said that if my EA hit them up more than 5,000 times in a day, that they would "talk to me about it".

Question answered now, thx.

Hello everybody,

I would like to know if there is a way how I can limit the maximum number of open lots in my MT4, ie for example I want that the total number of lots does not exceed 4 standard lots.
This is because I have an EA that continues to place trades in the same direction until it closes all of them in overall profit. If there is a big move in the opposite direction of my open trades, the EA will continue to open trades with increasing lot size, the EA places a 0.1 trade and if it does not close in profit, it opens a 0.2 trade, then 0.3, 0.4, and so on.
If there is no limit and the market does not retrace, it can cause a margin call in my account.

Hope you understand my point and hopefully someone can help me.

Regards,
Sandro

Unless the limit is built into the EA, there is no way to limit the number of open lots until it hits your margin limit. Look for a parameter like MaxLots or MaxOpenTrades or MaxLevels. Some EAs have this capability and some don't.

The limit is broker dependent. This is to prevent someone, using an EA, to flood their data server so much so it slows down their server.

As you see, the broker could only have a handful of server to process your orders. Clients could have as many "client platform" running simultaneously and flood the server. This is called Denial of Service (DOS) attack. Do this and the server will not be able to receive the correct updated-realtime market price.

I remember a friend getting reprimanded/warned because the broker thought he was doing this when his Trailing Stop EA was quickly changing the SL. Of course the friend wasnt flooding the server.

Bottom line, do ask the brokers about it first. You dont want to make win trades only to find out later that the broker will throw this against you and forfeit the money.

Can anyone list up brokers (well known major brokers ) you know with no limit except Go Market? I contacted Go Market right before and they confirmed they still don't have limit...

I'm pretty sure any ECN broker doesn't have any restrictions on number of open trades. It's all new to me but I have started looking into this after reading another thread.

You are pretty sure? You are pretty wrong!

It is mostly 200 open trades+pendings per account.

MT4 does not have any limit. The limit of 200 open trades are imposed by broker to ensure that their server can handle the load. Popular broker like ICMarket has a limit. Choose less popular broker and they won't have a limit. I know of several Australia brokers that dont. Good luck in your search.
