Everyday 0003 _ MAC Pullback

393
I recently posted a Moving Averge Crossover strategy for my Everyday project - a project I've given myself where I try to create one strategy everyday in between 15 minutes and 2 hours.

In the comments of my last published idea, user SignalTradersUK was very kind and suggested I try the following in my next study:
"i think your next study should be, to workout what to do after the Moving Average cross! If you look just on the chart you have posted, Price would appear to always come back to the levels where the 2 MA's cross and then go back in the direction of the crossing of the MA's. It's a great pull back strategy."

I'm really just beginning to learn about coding strategies so I'm not 100% sure I correctly understood his suggestion.
I admit I had difficulties wrapping my head around how to do this.
Anyway, the result is a strategy which runs alongside the main Moving Average Crossover.

'The Algorithm'
When the fast and slow MA cross the strategy traces back 40 days to find a swing low.
This swing low and the price at the MA cross is used to calculate a fib 1.272 extension.
The price at this 1.272 extension is used to place a Pullback short order.
Since we're shorting a bull trend, a tight stop is used.
If the pullback reaches down to the fib 0.618 we take profit (close the short).

Like I said, I don't know if I correctly understood SignalTradersUK feedback, but I really appreciate the
feedback and advice!

As always I'm hoping to learn from the community, so all feedback, corrections and advice is very welcome!
Thanks!
