This is either a simple question, a complex question or a trick question. Why don't you simply look at the chart? I know you will not get 100% accuracy since you are doing demo trading, and there is slippage to consider when doing live trading etc. But it is a very good indication of whether your stop has been hit or not.
if you insist on not looking at the chart, then yes, go through all quoted prices (minus or plus spread + broker commission depending on buy/sell order) after you enter until it is near to your stop loss or take profit point. If it hit pass the points, then write down the exit price.
how is he going to get those quoted prices, spread, commission ....? if he is on demo trading, he probably doesn't have those data ( those data are not free ). he can get a free chart. but he refuses to look at the chart.
If you only have the data you describe, you can't know without looking at a chart. But there are demo accounts from almost every broker out there that will do this for you.

If that is too much asked, I advice you to stop trading and find some other job that asks no efforts. Your "problem" is irrelevant compared to the real problems you will still encounter in your journey to profitable trading.
You can find that out by looking at the charts. I don’t think it’s difficult to spare a few minutes to look at the data on charts.
