I want a robot created based on daily OHLC

hi,

I want to create a robot that plots previous days high low open and close based on server time.

1.it should not alter or close manually open positions 

2.it should allow me to adjust EA'S positions if i wish to

buy condition:

a.it should open a buy order if the candle closes above the previous day's close but close the order if it reverses below the line

b.if the buy order didnot cross below the line and even crossed the previous days high then it should close if price reverses below previous days high

sell condition:

a.it should open a sell order if the candle closes below the previous days close but close the order the price reverses above the line

b.if the sell order didnot cross above the line and even crossed the previous days low then it should close if price reverses above previous days low

3.it should have trailing stop loss function

any other queries and additions or adjustments we will discuss once the product is getting developed.
