You can clearly see that A and B is a resistance level and 3 is the completion of bullish three drive pattern which results a 1.272 extension of B. Second TP should be around 1300 if it breaks the trendline.
The requirement for a gartley pattern is a 0.618 retracement of point B and 0.786 (0.7855) retracement of XA for entry point. BC projection should be either 1.272 or 1.618 which in this is 1.272 (0.7876) https://www.tradingview.com/x/wyNHFp3M/
