Need help with trading bot functionality

Hi @askmike, thank you for your reply.
I'm not a developer, so it's hard for me to understand everything from that thread. 
Can you help me just understanding how I can: 

- get the last price traded: 

Code:

this.lastprice = ???

- get the buy/sell information:

Code:

// If I bought = 1; if I sold = 2
//
if (???) {
this.buysell = 1;
}
else if (???) {
this.buysell = 2;
}

Not least, if I place a manual order on the exchange (so not made by Gekko), will this ontrade function get the information too?


Thank you!
