Narrative:

It was an uneventful take off. I was handed off to approach by tower. A controller vectored me left. The airplane was on autopilot and I dialed in a left heading. The plane started turning to the commanded heading. Moment[s] later; a different controller came on frequency and told me to disregard and turn right to an assigned heading. This was dialed into the autopilot. About four minutes later; the first controller came back on frequency and abruptly tells me to turn left to an assigned heading. This is programmed into the autopilot. The plane starts turning. Immediately thereafter the different controller comes on and says to disregard instructions and turn right to an assigned heading. This is put into the autopilot; the plane starts turning.moment[s] later the second controller came back on frequency and said to immediately turn right with urgency in his voice. Simultaneously I got an audible and visual traffic alert on my garmin 600 EFIS. Since the plane was already in a standard bank turn. I had to disengage the autopilot and manually steepen the turn in IMC and turbulent conditions. The remainder of the flight was uneventful. The first controller never came back on frequency. When I landed; I called the watch commander of the TRACON. He apologized for the incident and confirmed that the first controller was a trainee. I asked him why they would be training somebody in the busiest airspace on earth at night in IMC. He informed me that this is standard. In terms of preventing this in the future; I think the only solution I have is to avoid new york at night with IMC. I obviously have no control over the vectors I am given by ATC or the experience of the assigned controllers.
