Candle recognize questions - page 2

[faustf]

Jean Francois Le Bas:

ATR(140) for GBPUSD might be 0.00200

and for GBPJPY it might be 0.20000

ATR reflects the volatility of the pair, but also the relative size (price value) of the pair.

so it's a good indicator of the "size" of one candle

it adapts to the volatility as well as the value of the price

for example how do you know if a candle is "big" or not ? because the size means nothing.

well you can compare it with ATR AND the price itself

if you divide the ATR by the price, you got a normalized value that can be used to determine is a candle is "big" or not

for example:

"mul" is the min size you want.

hope it helps
