Indicator in EA and more

Hello everyone, 

I use an indicator in live for trade wok good. I need to convert the indicator in EA, but i need help developper for perform the indicator : 

1/ 

Two possibilities :

- when arrow green appear the EA buy position, if new arrow green appear below the previous the EA open new buy position, but if new arrow green appear above dont open. waiting arrow red appear close position and open sell position 

- when arrow red appear the EA sell position, if new arrow red appear above the previous the EA open new sell position, but if new arrow red appear below dont open. waiting arrow green appear close position and open buy position 

2/

This indicator never repaint, never recalcultate, never lag. but sometimes when market up more or down more bad signal. If a developper can me find other indicator reversal (no lag no repaint no recalculate) and combinate with my indicataor for realize better performance or delete bad signal im here. 

The budget depend on two things : the first step for a developper its easy to realize, so price is normal, but if you find solution for indicator is better (second step) the budget can be lot of more
