Ok, I assume you are referring to the last three white candles…
At times price is moving quick enough that when one candle closes and the next one draws that it “gaps” up or down as the new candle is drawn… especially on short TF charts (like the 1min displayed) It’s just the price feed still flowing in the milliseconds the platform is generating the next candle…
On this particular example, it’s a very small amount, maybe ~0.3 - 1 pip while the new candle was drawing…
