Simple expert for boom and crash raise on moving average

Simple expert for boom and crash 

Okay so first of all this expert allowed to open buy positions on boom 300,500,600,900 and 1000 and also open sell positions on crash 300,500,600,900 and 1000

Expert raise on Moving Average 10  exponential apply to close we use time frame 5 minutes

Entry rules its for boom buying 2 points above ema 10 , and for crash selling below ema 10 

when open position set stop loss 7 points below ema 10 for boom positions , and 7 points above ema 10 for crash postions

my strategy raise on spike so i want to set up tralling stop loss  5 points after spike

Remember the most imporant rules this expert should trade full automatic 

so put buy and sell position and set stop loss after open it 

I want also set lot size by my own, and remember also ea should be allowed to put only 1 position per index in the same time
