Modify EA to take inverse trade

i need the EA to take reverse trades.

that is if the EA generates a buy signal, a sell should be opened instead and vice versa for Sell.

also, 

as i need the entry and exit logic i nee it to be modified

presently,

if SL is set to 3, when there is a 3 consecutive bull candle, a buy trade will be opened at the close of the 3rd candle and when there is a 3 consecutive bear candle a the buy is closed and a sell is opened immediately.

for TP , if TP is set to 5, trade automatically closes at the end of 5th candle.

modification that needs to be made

separate the entry from exit

leave  SL and TP rule just to close trades either trades hit stop loss or take profit

entry Rule variable

if  is set to 3, when there is a 3 consecutive bull candle, a buy trade and vice versa
