Hey,

For Buy:

- Loop count every 3 candles 

- Find the lowest value of that 3 candle loop

- enter position at the third candle, for stop loss use ask price calculated by the lowest value.

Functions, functions and functions.

One of the reasons why this system wont work.

There are no time intervals, your trading activity would be continuousely chopped by the market.
