Only watched the first few minutes.
No need to be long & short.
Current price = A.
Place a sell limit 100 above A (pt. B) and a buy limit 100 below A.
When price reaches B you now have a short (same exposure as his method). Place a buy limit at A and sell limit at C.
When price reaches C you now have 2 shorts (same exposure as his method) so place a buy limit at D.
When price reaches D you have a profit of 100 plus an open short at break-even (same profit & exposure as his method).
Keep adding limits as new orders are filled.
Having long & short at the same time is madness (with the exception of a few traders that scalp inside their swing trades). Closing a buy position at pt. B and immediately opening a new buy is madness (unless you enjoy feeding your broker).
This is just a grid martingale system. Works best with ranging/choppy markets but strong trends like Yen recently and you'll be sitting on sizable losses.
