Adjustment of an existing EA - adding the function of searching for a special order of positive and negative candles

I need an adjustment of an existing EA. 

The EA is now searching for a combination of two positive and then two negative candles (I call it "formation") in the chart (or the other way around - two negative and two positive candles, depending on desired trade direction). 

In addition to this combination of 4 candles, I want the EA to include several more candles into the formation. 

- I want to be able to tell the EA to search for example for 6 more positive candles before the formation (or 8 or 10 - depending on my settings in the parameters). 

- I want to be able to define how many of these 6 candles are allowed to have the opposite direction (if I enter "1" into the parameters, 1 out of these 6 positive candles might be negative and the trade should still be done)

- I want to be able to exclude candles with a high volatility (e.g. if difference between open and close is 5 pips, but the difference between minimum and maximum price within this candle is 50 pips - then the "body" of the candle is only 10% of the complete candle. So I want to be able to tell the EA to NOT trade, if the body is e.g. 10% or less than the complete candle. 

- In the original EA there is a function, that a trade should only be done, if the formation is higher (or lower - depending on direction) than the price at the time of activating the EA. I want to be able to switch this function off. So a trade would be done always, once the "formation" is found - no matter whether at higher or lower price compared to time of activation.

- I want to include a function to automatically move SL to BE at a certain level

- I would like to be able to set a time, when the trade would be automatically closed, in case SL or TP was not reached until that time.
