Can Gekko make decisions based on purely OCHL?

[streetlaw]

I'm trying to set up my strategy so that it can buy when price is X amount of USDT above the previous candle's high and sell when price reaches my target, ex. my entry price + my target.

I don't want to use any indicators at all. Is it possible to make trades based on the previous candle's OCHL data and the current price?

Thanks.
