EMA EA

Hello

 I need an EA built that will:

a) buy if a candle closes above the ema

ab) close the trade if the candle closes under the ema

b) sell if a candle closes below the ema

bb) close the trade if the candle closes above the ema

The period of the ema and the lot size needs to be user configurable. Depending on difficulty, it would be preferable to allow partial closes of the trade for example +50 points = 1/4 close. +100 = a further 1/4 close etc until the last 1/4 is left to be closed by the above mentioned candle closing above/under ema.

It will also be necessary to close 1/2 of the position at (for example, user definable) -100 point loss.  One trade will be open at all times using this method.
