An inside day is often used to signal indecision because neither the bulls nor the bears are able to send the price beyond the range of the previous day.
The pattern when found near the end of a prolonged uptrend may suggest that the rally is getting exhausted and is likely to reverse.
However, wait for a breakout/breakdown from the pattern-- 11738-11645 ---to see whether Nifty is reversing or continuing the Uptrend.
