Hi
I am wanting to run multiple accounts on my VPS. Each account with it's own EA running. When I switch accounts, my EA opens on the account i login to. I need it to continue running on the original account. How do I stop this from happening.
Thanking you in advance
Aldo
A MetaQuotes virtual host can only host one trade account at a time, so you will need multiple virtual hosts ...
If using 3rd party VPS, then a single MetaTrader desktop terminal can only run one trade account at a time. So you will need to run multiple terminals (maximum of 32).
Hello everyone.
I started to study MQL4 last week with the intention of making something similar to the Magic Keys device.
Reading the MQL4 manual raised some questions and I was wondering if someone could help me to solve them.
I wonder if it would be possible to create a macro so I can select the rectangle tool and draw in the chart.I would like to
be able to activate/select some of the tools that have no shortcut in the mt4 plataform from a macro pad.
Is that possible? If so, could you tell me what do I need to learn or focuss my attention on?
Thank you.

Good day everyone,
I am experiencing some problem which I find difficult to explain and hence difficult to find a working solution from the Codebase and forums. I have an indicator which runs well when back testing but when I place it on a live chart, it shows/draws bogus arrows. If I recompile the code while the indicator is placed on a live chart, the bogus arrows become even more. I am thinking that somewhere in the code I have to delete old data from buffers/arrays or set them to empty values, but I don't know how to do that because I don't understand what is causing the bogus arrows.
Please see image below:
The code is below, I have excluded the unnecessary if conditions which in the end only set bool variables to either true or false.
Your assistance in explaining why the bogus arrows appear and showing me how to get rid of them is much appreciated.

I found the solution, and now I see how simple it was. Before the indicator runs, clean all buffers. Since you would like to do this only once, clean the buffers at the instance the indicator is first dropped on the chart, and that would be when prev_calculated is zero. See code below:
I looked all over the internet but all the API's I could find were either just wrappers that still needed a terminal or were just really expensive.
So I am making my own API that won't need a terminal and will work on any platform. And I wanted to know if anyone else would be interested so I could develop with the public in mind.

This section is about MT4, not MT5.
You can't do such API legally. MT5 servers require an MT5 Terminal or official WebTerminal to connect.

You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit by the Ask.
Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?
Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close at a specific Bid price, add the average spread.
MODE_SPREAD (Paul) - MQL4 programming forum - Page 3 #25
The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes.
My GBPJPY shows average spread = 26 points, average maximum spread = 134.
My EURCHF shows average spread = 18 points, average maximum spread = 106.
(your broker will be similar).
Is it reasonable to have such a huge spreads (20 PIP spreads) in EURCHF? - General - MQL5 programming forum (2022)
Magic number only allows an EA to identify its trades from all others. Using OrdersTotal/OrdersHistoryTotal (MT4) or PositionsTotal (MT5), directly and/or no Magic number/symbol filtering on your OrderSelect / Position select loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

You need one Magic Number for each symbol/timeframe/strategy.
Trade current timeframe, one strategy, and filter by symbol requires one MN.
If trading multiple timeframes, and filter by symbol requires use a range of MN (base plus timeframe).
