i love your way of analysis of this strategy but i want to give you few advice if you would take them.
1.try to also use pivot point analysis to corroborate your support and resistance analysis it works very fine.
2. Don't make the mistake of taking support and resistance as a price point but rather as an area. What i means by this is that assuming a resistance line falls exactly on 1.4459 don't take this price as your resistance point but rather give a margin of error of like 10 to 15pips hence you take the resistance area as between 1.4444 to 1.4459 it can save a lot of trades
