consecutive magic number partial position

Hello,
1. I want to execute a partial position with each long signal. The EA should generate a consecutive magic number. Problem: When I use a Long Rule, I forgive e.g. “1000”. The EA would normally put only “1000” with each buy signal at Rule1. He should but for example 2. Long “1001”, 3. Long “1002” etc put.

2. The size of the individual positions should be 0.5 percent of the equity + 50% of the current open long positions.
To calculate the stop, use EMA100.
How can I do that ?
Thanks for your answers
