Simple ea using EMA and Bolinger Band

i need an EA to execute trade based on the parameter of BB and EMA.

for buy trade

when price close below or on BB lower band and the price is below the EMA at a distance according to preset. a buy trade should activate and close the trade when price crosses the EMA above, NOTE that the EA should also open multiple buy as candle keeps closing below BB, on a multiple lot.

for sell

when price close above or on BB lower band and the price is above the EMA at a distance according to preset. a buy trade should activate and close the trade when price crosses the EMA below, NOTE that the EA should also open multiple sell as candle keeps closing above BB and price above EMA, on a multiple lot untill target exit is met at the cross below or above the EMA or a certain amount in profit is reached according to preset.
