Execute only once while condition is present  [SOLVED]

I think similar questions have been asked, but nothing specifically about what I'm looking for:

Let's say my strategy is to buy when RSI > 70, with some kind of profit condition and stop loss. Dummy code would look something like
If I'm on the wrong side of the trade, I want this to only execute once. In other words, if the stoploss is hit, I don't want to execute another Buy even if RSI remains > 70. However, if RSI goes below 70, and then goes above 70 again, it's a new condition, and the then-statement should get executed.

is this possible? I tried using various loop logics, but the compiler doesn't let me place an order command inside a for loop. I thought that `once` might work --
... but it doesn't.

What you should be looking for is the first instance of RSI crossing into 70+.

What a great example of how you just need a second pair of eyes on a problem sometimes. I was deep in the for/while/repeat-loops weeds and complex counters. I can't believe I was so blind to . Thanks!

Another way to code this logic:

Another way to code this logic:

Code: Select all

If RSI > 70 and RSI [1] <= 70 then . . .

Is there an advantage of doing it this way (computationally or otherwise)?

They should produce the same result. No advantage to either.
