conclusion

Draw the line (horizontal, slope & channel)

Break slope, make horizontal line and channel.

What position it is? sideways, uptrend, downtrend?

Pass (break) & stand or not?

How much margin do you need?

How many time it test the barrier? (to say if it still on older direction or try to start a new one.)

How the shape of MACD  line?

Break the line (and stand) mean follow through. (The trend still.)

avoid sideways as much as possible (unless it have enough margin)

If not enough margin, wait.

If not sure, do nothing.
