we always ask about what happened in history of a symbol during range zones and
how many times
price bounced between two price of a range zone?!
this is what i define as bounce number. it can be calculated by a statistical analyses of any symbol history from market.
to be more clear lets have a look to image no. 1.
image no. 1: definition of bounce number, its goal and applications
image illustrates how price movement generates statistics of bounce number tool. to have a delay on tool i generated it as an ea to use sleep function. this function somehow prohibits crash on chart because of higher number of candle set on tool's input.
the other image (image no.2) shows tools very brief graphical structure and its objects meanings.
image no. 2: bounce no. statistics.
tools usage:
form image no. 2 considering we set
bouncing channel half height
to 600 points :
- there are 6 different bounce numbers from 1 to 6 for this symbol.
- bounce number 2 means, price starts from middle of bounce channel (height 2 * 600 = 1200 points) and moves up and down also hits one time red and one time blue lines before hitting tp=1200 points. so for bounce no. 5 this means price starts from channel mid point and hits 2 times red 3 times blue or 3 times red and 2 times blue line then hits tp=1200 points. same can be said for other bounce numbers.
- we do not have bounce number 7, means there is not any 7 times bounce between red and blue lines (with 1200 points distance) over all history selected in tool's input. please consider that if you select more historical data (
max number of lookback candles
), chance to find 7 bounce will increase. but as we see even chance for 6 bounce is 22 in 9020 total items of price hit tps.
what is in input of tool:
- max number of lookback candles
: same as other scanning tools be careful about number you set for this cell. do no increase it dramatically to avoid any crash in memory.
- time-frame:
time-frame of candles e want to use to find bounce from channel limits and also touching of tp lines. use a lower time frame for thin channels. if you do not know what to set better to use m1 time-frame.
-
bouncing channel half height:
this is green line's distance from red and blue lines. it is in points.
