Keeping First Buy/Sell Signal

[aligator]

Dear Support,

A simple indicator draws many buy and sell arrows when price is above and below RSI 50 line.

I am looking for a sample script that will keep only the first instance of a buy signal and will not draw another buy signal until after a sell signal, and so on.

I know we can use a crossover method for the case of RSI, however, I am looking for a method in general to keep only the first instance of a signal until after an opposing signal is generated.

Many thanks.

Hello aligator,

Thanks for your post.

We do not have a helper method available for this task, but you could use bools to control the logic so it only occurs once until the some other logic resets the bool. For example:

private bool SingalActive = false;
protected override void OnBarUpdate()
{
    // Our signal which should only be fired once.
    if (Close[0] < Open[0] && !SignalActive)
    {
        //Do Something once here. It will happen only the first time this condition becomes true.

        SignalActive = true;
    }

    // Opposing signal, when the bool should be reset.
    if (Close[0] > Open[0] && SignalActive)
    {
        //Do Something once here

        SignalActive = false;
    }
}
