On Tick vs OHLC vs Opening Price

[deathkid13]

Hi guys , I just wanna ask if does modelling affects meta trader optimization speed , efficiency and results??

If yes , which one do you use that provides good results and can speed up your testings??

Thank you!!

PS. If you can share some tips and tricks to speed up optimization , will be appreciated very well. Thank you

In case of MT4:

If EA only open trades at bar start, backtest with opening price is OK. But the SL TP may not be accurate enough. A final check with OHLC is needed.

If EA would open trades within bar, backtest with opening price is USELESS. At least using OHLC as a rough test. On Tick backtest is a must.

My experience:
In the second case, a OHLC backtest with profit factor, say, 1.6, would turn out in On Tick backtest to be, say, 1.3
The so called On TIck backtest seems to be using the minute data only (i.e. not real tick, just estimations for ticks)

Agreed. This is why I moved to optimization on MT5. Ticks are really considered there.
