Floor trader indicator

I need a simple indicator. Inputs are 2 EMA. The indicator runs on open candle. Checks back the last N candle(N max 10).

Gives 3 values for BUY(0/1/2) and 3 values for SELL(0/1/2 ) in histogram.

Buy 1:

(From candle0 to t candle N any candle Open is >= EMA2)   AND

(From candle0 to t candle N any candle Low <= EMA2)         AND 

(From candle0 to t candle N any candle Close is >= EMA2)  

Buy 2:

(From candle0 to t candle N any candle Open is >= EMA1)   AND

(From candle0 to t candle N any candle Low <= EMA1)         AND 

(From candle0 to t candle N any candle Close is >= EMA1)  

Sell  1:

(From candle0 to t candle N any candle Open is <= EMA2)   AND

(From candle0 to t candle N any candle High is  >= EMA2)    AND 

(From candle0 to t candle N any candle Close is <= EMA2)  

  Sell  2:

(From candle0 to t candle N any candle Open is <= EMA1)   AND

(From candle0 to t candle N any candle High is  >= EMA1)    AND 

(From candle0 to t candle N any candle Close is <= EMA1)  

There are 2 filters for signals:

Filter 1:

In Buy direction ( EMA1(0) >= EMA1(1))  AND  ( EMA2(0) >= EMA2(1))  

Insell direction   EMA1(0) <= EMA1(1)  AND  EMA2(0) <= EMA2(1) 

Filter 2:

In Buy direction EMA1 >= EMA2

Insell direction   EMA1<= EMA2 

Calculation decimals are rounded to 4 decimals. So for example 1.45634 = 1.45633 in calculations.
