Market Scanner using Half trend Indicator

I have the following requirement of a market scanner:

In Mt 4 , make an indicator to scan all the symbols from market watch window ( Forex

and CFD instruments ) and produce a table with symbols that have a fresh signal*

from the half trend indicator ( the indicator is provided as mq4 and we should be able

to choose the indicator parameters before the scanning begins ) .

*Fresh signal means that the scanner result table must include signals that were

generated up to X candles before (X is variable and we should be able to choose between

1 and 20 candles before. For example if we choose the number 3 , the table should

include the signals that were generated 3 candles before , 2 candles before and 1 candle

before)

The results must be in multiple time frames , 1 min , 5 minute , 15 minute , 30 minute ,

1 hour , 4 hour , Daily , weekly .

** Since we are looking only for fresh signals only some of the timeframes and some

of the instruments will provide fresh signals. The timeframes where there are no

fresh signals must be left blank .

There must be an option to refresh the table after some minutes so we do not need to

remove the indicator and replace it to refresh.
