I'm trying to implement a monthly system that buys the top 3 ETFs on a certain day of the month. If I just use the formula Rule1 = (Day()) == (1)); sometimes I don't get a buy signal because the first trading day of the month is either on a weekend or a holiday. How can I determine if this is the case?

Rule1 = Day() > 1 and Day() < 7;

Actually that doesn't work because Rule1 will be active for multiple days. After I posted I figured out how to do it: I created a C# function called FirstTradingDOM.

Then the system uses: Rule1 = FirstTradingDOM;

You can also use:

rule1 = month() != ref(month(), 1);

What if I want to buy/sell on another trading day of the month (e.g. eighteenth day of the month)?

rule1 = month() != ref(month(), 1);
rule1 = ref(month(), 7); // For the eighteenth day of the month

I don't understand why it would work, can you explain this simple code?

My mistake. It should be:

rule1 = month() != ref(month(), 1);
buy = ref(rule1, 6); // For the bar number 7 after the new month

    Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
