why are simulator candles smoother when using older dates?

for quite some time now i frequently practice on mt4 simulator, LHF simulator to be precise, and now as an instinct i can guess where price is to go.

here is the video of me doing it,

however here is the problem, in simulator the candles are smoother as in the the flow nicely and are less jittery -observe the video-. this is when i use older than 2011 dates.

but when i am using recent dates the movement is very jerky. naturally i would want to see the trading days candle play it again and again to get a trading signal.

how can i smoothen the movement of candle in strategy tester just like in the video. i am even ready to pay any one who can do this for me

Make sure you have lower time-frame data (M1) for all the time periods you are testing. MT4 uses the lower timeframe data to more accurately model the price movement. Ultimately, you will still have 'simulated' M1 data unless you use a third party application to create a real tickdata data test file.

honestly Iam not aware of such technical details of Backtesting all iam looking for is someone to code me an EA that can simulate the candle of the day as smoothly as. Shown in the video
