Moving ama buy and sells mt5

im looking for a simply ea that has 2 * average moving average lines (lets call one red line and one green line)... must be able to change the settings of both  lines, and i want one to be able to apply to previous indicator data, something that can be done on the charts bbut not an option when using the expert ea maker...

when then red line crosses above the green line needs to buy, and when it crosses down it should close that trade and sell and visa versa. these main trades should only open and close on the crossing of the two ama's not the price going over the ama's.

also, if its in a buy, ie red above green and the price line moves below the ama than a sell needs to be opened with a trailing stop (adjustable), if price reverses back to the line without being cut off by the trailing stop then this trade should be closed when the price crosses the ama, another buy should then be opened as long as the red line is above the green this needs to have a greater trailing stop (changable), this one should also cut off if the price hits the ama line... and visa vers for both buy and sells...

if the 2 ama lines cross, i.e the green crosses above the red then all buy trades should be closed, and visa versa for when the line cross over the other way.  

for the trailing stops, i want to be able to choose 2 figures, so if the general direction is buy, and a sell is opened i can choose a smaller stop i.e 5 pips, but if a buy is opened the trailing stop can be a different fiqure say 20 pips, id like these to be adjustable for testing.

i hope this all makes sense, any questions please let me know

thanks
