Easy job: add three simple features to my EA

my simple EA for semi-autotrading needs an update...
..is based on stoch-rsi

add three simple features:

1. trade only in the direction of the trend

on/off
trend: ema 1-300 (variable)
only buy: when the price is above ema
only sell: when the price is below ema

2. trailing stop (in money, not pips)

on/off

i would like to set e.g.
wehn my trade is 15$ in profit,
set a SL at 1$ pofit
and trailing 2$-steps or without trailing because TP

3. news filter

on/off
do not open a position x hours befor and after high impact news (from the majorrs)

I would be very happy for further ideas and help :-)
