identify bar just before a strong move up or down

Is it possible for a study to be created to identify a pair of bars where the second bar has a strong move up / down?

then draw 2 lines towards the right from the open of the previous bar and from the low/ high of the previous bar.

the body of the previous candle should be small. (about 20% smaller than the difference of highlow.

code from blastoff trigger :

input trig = 20;

def val = absValue(close - open);
def range = high - low;
def blastOffVal = (val / range) * 100;

the difference between the high low of the second candle should be at least twice the difference between the previous candle's high low.

the second candle should be closing way higher or way lower than the previous candle

Hopefully this gets you started.

The percent input is to help def 'way higher or way lower'.

input showcloud = yes;
input percent   = .1;

#Up =====================================================================
def blastoffup = if ((high - low) > (high[1] - low[1]) * 2) and
                      close >= open and

                      close > close[1] * (1 + percent / 100) then 1 else 0;

def hup        = if blastoffup then high[1] else hup[1];

plot hblastup  = hup;
hblastup.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
hblastup.SetDefaultColor(Color.GREEN);

def lup        = if blastoffup then low[1] else lup[1];
plot lblastup  = lup;
lblastup.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
lblastup.SetDefaultColor(Color.GREEN);

AddCloud(if showcloud and hblastup then hblastup else Double.NaN, lblastup, Color.GREEN, Color.GREEN);

#Down ===============================================================
def blastoffdn = if ((high - low) > (high[1] - low[1]) * 2) and
                      close < open  and
                      close < close[1] * (1 + percent / 100) then 1 else 0;

def hdn        = if blastoffdn then high[1] else hdn[1];

plot hblastdn  = hdn;
hblastdn.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
hblastdn.SetDefaultColor(Color.RED);

def ldn        = if blastoffdn then low[1] else ldn[1];

lblastdn.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
lblastdn.SetDefaultColor(Color.RED);

The concept is there , I probably only need to mess around with the definition of blastoffup and blastoffdn from here , ty sir @SleepyZ

There are stray lines at the bottom of the graph sometimes though , any idea why

The following should remove the stray lines likely caused by using a prior bar needed at the beginning (eg: high[1]) did not exist.

The hup[1] (lup[1],hdn[1] and ldn[1 as well) ]is a recursive and is needed to plot the extended horizontal lines. Otherwise, the plot would be over just the 2 blastoff bars.

Pretty cool, I like it, thanks.
