/* my entry is very simple(daily data for trading)

kpl system for entry only & exit as follow:

1 st exit at x % from entry price only 1/3 quantity.(ie 1st profit target)
2 nd exit when exit Signal comes from kpl sys remaining 1/3 quantity.
3. scale-in to initial quantity if new kpl Buy Signal comes.
re-do above scaling-out & scaling-in till filal exit.
4. final exit all quantity when Close below 21 Day EMA.
