If your broker uses a suffix (e.g. EURUSD.a) you should change the ‘Symbol Suffix’ parameter to the suffix of your broker. In this case, it should be changed to .a instead of a blank value used by default.

There is a slight probability that after installing the EA and trying to load it on your trading chart you get a ‘License error’ message displaying on the EA interface.9 out of 10 times, this is because you did not add the correct URLs on the EA settings, so before anything please make sure you do that.Here you have a step-by-step tutorial video on how to fix the "License error!" message:Click here to watch videoAnd a break-down of each step with images, in case the video is not enough:1.

You only need to install one copy of the EA to trade on all pairs listed in the 'Symbols' parameter. Please, remove the excess copies, and the EA will work.

To solve this problem, please, do the following:1. Make sure the “AutoTrading” button is pressed.2. Click on the icon near the EA title in the upper right corner of the chart. There, go to the “Common” tab and make sure the “Allow live trading” tick is active:    a. On your MetaTrader platform, head to the menu on the header and click on “Tools”, and then on “Options”           b. Head over to the “Expert Advisors” tab and click on it          c. Check the “allow algorithmic trading” box        

This error means that you placed the EA that is optimized to trade on the M5 timeframe on the chart with another timeframe - for example, H1. So, the bars of your chart contains hourly data each, while the EA needs the chart with bars that contain 5-minute data. Just switch the chart timeframe, set the EA on it, and it should work.

There may be a couple of reasons for it. Depending on the reason, there are several potential solutions. Here are all of them:1. Make sure you have at least these values in the MetaTrader settings. Having less might result in such errors (see screenshot)2. Make sure that all pairs you wish to trade are in the Market Watch.3. If both are correct, click through all the timeframes of every pair this error happens on.4. If that doesn't help, reinstall the terminal.

In most cases, this error means you've installed the EA on a symbol of your broker that's not tradable. Some brokers use suffixes on their tradable symbols, such as EURUSD.a instead of EURUSD. In this case, you need to install the EA on a chart of a tradable symbol (in this case, EURUSD.a) and also set the 'Symbol Suffix' parameter to .a to solve this issue. You may be confused as to why brokers do that. In some cases, brokers need separate trading pairs for indicative purposes (e.g., to calculate technical info, like your deposit load and margin level) and another set of pairs to be traded. In this case, they do it by making two sets of pairs - indicative ones without the suffix and tradable with it.
