Clarrification/adjustments on "so easy its ridiculous" system

The two major points I want to hopefully obtain clarrification on is indicator setting across multiple timeframes, and considering the use of ATR in regards to SL.

So the site shows settings for the daily example as follows:

5 sma
10 sma
Slow stoch (14,3,3)
RSI (9)
Sl 100 pips

For cowabunga on 15m
5 ema
10 ema
Stoch (10,3,3)
RSI 9
SL set by previous relavant low/high

First of all, ema or sma? Is this adjustment due to using different time frames?

Second, stoch(14,3,3) vs (10,3,3). Is this again a time frame adjustment?

Third, the macd used in cowabunga uses (12,26,9). Does this translate from daily to 4hr? I’m not really looking to duck under the 4hr chart. Just looking to see if these settings are effected by timeframes.

Fourth, I dont care for a set 100 pip SL. I did some manual backtesting and it seems to get triggered quite often. I can appreciate actually looking for a better location for a SL but wondered if anyone has used ATR(14) to better find the current pip range per candle and apply a multiplier to that value?

I want to essentially see which settings could/would be effected from an indicator standpoint in relation to time frame.

Thanks guys!
