Super Trend Exploration AFL For Amibroker

I'm seeking a developer to create an Amibroker Exploration that will filter the stocks based on SuperTrend. The AFL will list out all stocks as BUY when Supertrend is GREEN and the price has closed below the rounded price as explained below. The AFL will list out all stocks as SELL when Supertrend is RED and the price has closed above the rounded price as explained below. Inputs Required: - SuperTrend inputs required. Default is 14 and 3. - Time Frame - Current chart time frame. - Rounding Factor input required. A factor of 1 means, For BUY the AFL will add 1 to the current supertrend value and will round off to the next higher round figure. If supertrend value is 279.13+1=280.13 which will be rounded off to 281. The AFL Exploration will list out all the stocks as BUY when supertrend is Green and the recent bar has closed below the rounded figure. For SELL the AFL will subtract 1 from the current supertrend value and roundoff to the next lower round figure. If the supertrend value is 279.13-1=278.13 which will be rounded off to 278. The AFL Exploration will list out all the stocks as SELL when supertrend is Red and the recent bar has closed above the rounded figure. Similarly, a factor of 2 means, supertrend value +2 rounded off to the next higher round figure. (For Buy) and supertrend value -2 rounded off to the next lower round figure. (For Sell)
