Hi everyone, I am a rookie and trying to grasp the functionality of the backtest function. I am having a little trouble coding this strategy and would really like to test its
record.

I would like a buy order on a williams%R with a 72 period cross over of the -75 line in the previous day, and the sell order for that should be when will%R crosses the -20 line

I would like a short order on williams%R with a 72 period cross over of the -15 line in the previous day, and the cover order for that should be when will%R crosses the -80 line.

any help with this would be great.

Thank you very much.

Hi Michael,

Here is the formula to implement this strategy:
buy = cross(Willr(72), -72); // Willr crosses above -72. To get crosses below, just invert "Willr" and "-72"
sell = cross(Willr(72), -20);
short = cross(Willr(72), -15);
cover = cross(Willr(72), -80);

The default order is initiated at the open of tomorrow. If you want to reference the previous day in your formula, you can use the "ref" function.
Example:
a = ref(close, 1);

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.
