Code or Logic for identifying non retraced movement of X Pips

Hi
I'm looking the code/sample to find
How many pips price has moved in which direction (short/long) without retracing X Pips.

I want to enter into a trade if Price has moved 200+ pips in one direction without retracing 20 pips. I'm looking for code sample if not logic to code this. Could some one help me here ?

Thanks
