FIX AND MODIFY A COSTUME INDICATOR

i have a custom indicator that's based on two indicators ( Trading The Trend ) and ( BrainTrend2Sig ) I'm having some bugs with

1- slow initialization 

2- glitching on high time frames 

3- signal arrows are poorly drawn on the chart

4- alerts for position entry not working properly 

and i need to upgrade it by adding 

- stop loss line based on ATR multiply by numbers to draw it on the chart

- take profit line based on RRR 

- and I'm thinking to add an additional function( highs and lows )using ZIGZAG and FRACTALS 

- ADD buy and sell labels and price labels to the chart 

- change the arrows to something more fancy 

- prepare the file for mql market upload

and i welcome any other ideas to upgrade the indicator
