1 …Can MT4 accept and hold multiple Limit Orders placed over several Currencies or can it hold only one at a time.
2… If the answer to (1) is yes then do the orders fire-off in order of the limits as they are hit.
3…Is there a 3rd party app that is better suited to this task than MT4
4… In fact, is there a very good Order (Trade) Manager that can handle all aspects of the trades.
The trades are mainly short term (minutes, hours)
Many thanks
Yes
Correct
I don’t think so… last I used MT4 in 2010 it worked fine. There’s MT5?
Metatrader easily controls orders. My MT5 is running 9 Expert Advisors at once, can still add/execute/cancel trades manually.
The lag between orders will be the latency between your connection to your broker.
MT4 does execute all the things that you want and it does manage multiple orders and they will be triggered when ever the price hits the number on which you had set your orders, and the app is really accurate with that. Personally thinking, tradingview and tradingview based platforms can do it better because they can also alert you once a price is reached and then you can check the market and decide weather you want to get in the trade or not.
