Ichimoku-Hausky Trading system

This is a indicator with some parts of the ichimoku and EMA. It's my first script so i have used other peoples script (Chris Moody and DavidR) as reference cause I really have no idea myself on how to script with pinescript.
Hope that is okay!

I use 20M timeframe but it should work with any timeframe! I have not tested this system much so I would really appreciate feedback and tips for better entries, settings etc..

Tenken-sen: green line
Kijun-sen: blue line
EMA: Purple

Rules:

Buy:
IF price crosses or bounce above Kijun-sen
THEN see if market has closed above EMA
IF Market has closed above EMA
THEN see if EMA is above Kijun-sen
IF EMA is above Kijun-sen
THEN buy and set trailing stop 5 pips below EMA

Sell:
IF price crosses or bounce below Kijun-sen
THEN see if market has closed below EMA
IF Market has closed below EMA
THEN see if EMA is below Kijun-sen
IF EMA is below Kijun-sen
THEN sell and set trailing stop 5 pips above EMA
