What are these averages signify..?

There are "close ema" (appears after the close price of week, day & Hour), "High ema" & "Low ema".
High ema- staying above it indicates upward momentum; below it downward momentum but if it stays above close ema during this period, it could simply be a correction.
Low ema- staying above it indicates uptrend is intact; below it the downward momentum increases..a follow up action is required.
Close ema- as highs and lows can be manipulated, the close price which is used to calculate most of the momentum oscillators plays quite an important price factor. Simply put, market is in uptrend above it and it is in downtrend below it in those time cycles.
These emas become useless once a trend is in place and they come to play some roles once a correction sets in after "OB" or "OS" situations.
There are more averages below the pivot table with colour changes depending on thier prices.
Avg: is a simple average which gives equal weightage to "n" number of period. for eg: a 5-day avg is calculated using last 5 days closing prices thereby giving equal weightage to all the past 5 days.
ema:emas are exponential moving averages which is calculated using a mathemetical formula that gives more weightage to the more recent prices thereby considered to be more dynamic as well as volatile.
Whenever "ema" value is more than the "avg" value, it means bullishness and whenever the "ema" value is lower than "avg" value. it signifies weakness/ bearish.
3, 5 ,10 are considered for short term; 20,30 days are considered for medium term; 50, 100, 200 days are considered for long term. These can be experimented with as market is evolving all the time. More traders become aware of a certain method or a pattern, a likely failure is possible. So keeping an open mind but at the same time using our own experiences manifested as our "Intuition" can guide us tremendously.
