SMAs and Inside Bar strategy is very common as far as Technical analysis is concern. This script is a combination of 10-20-50-200 SMA and Inside Bar Candle Identification.
SMA Crossover:
4 SMAs (10, 20, 50 & 200) are combined here in one single indicator.
Crossover signal for Buy as "B" will be shown in the chart if SMA 10 is above 20 & 50 and SMA 20 is above 50.
Crossover signal for Sell as "S" will be shown in the chart if SMA 10 is below 20 & 50 and SMA 20 is below 50.
Inside Bar Identification:
This is to simply identify if there is a inside bar candle. The logic is very simple - High of the previous candle should be higher than current candle and low of the previous candle should be lower than the current candle.
If the previous candle is red, the following candle would be Yellow - which may give some bullish view in most of the cases but not always
If the previous candle is green, the following candle would be Black - which may give some bearish view in most of the cases but not always
Be Cautious when you see alternate yellow and black candle, it may give move on the both side
