I heard about Expert Advisors like Martingale, Grid & Fap Turbo - what mean EAs like that

I would like draw the lines as the (E)xpert (A)dvisor on Meta Trader 4 and refresh it every next bar. Let's use only 100 last bars. The green line should be drawn as the connector between two points: 1/. LOW of the last bar (always) 2/. LOWEST bar
