How do I know if I paper trade if the stop loss was hit before the take profit? It's easy. If you want to know, all you have to do is reply to this post OR private message me and you will find out.
drop to to lowest time/tick increment you have available and then fast forward. No easy way, we coded this function as part of our backtest engine.
My very first major computer science project was done entirely on paper (implementing an on-disk database.) The reason was that school computers were routinely unavailable and I didn't have a portable computer at the time. So I sat in the study carrels, wrote out the code, debugged all the edge cases on paper and when the computers were available, I typed in my code. Sans some minor issues, the code ran through all of the prof's test cases successfully. Still my best written code ever. A big fan of paper and pen... Not so much for trading, but maybe there is something I'm missing.
I bought a remarkable notebook to write down my daily plan but now it's so ingrained in me I just mark up the charts and watch youtube until alerts hit. So I guess the e-paper did the job it was supposed to. BTW, highly recommended notebook.
Yes, if you absolutely cannot look at a chart, you need to get data about trades in some non-chart form and estimate if/when your stop or take-profit order was filled and the price the order would have been filled at. This is how they used to do it.
You would never know. Even if you look at the chart, you would never know for sure your stop-loss would've been hit or not. If you are paper-trading with a demo trading facility provided by your broker, you might be able to tell by looking at its execution history IF the demo trading facility shows it to you and you might not even know if irl your stop-loss would've been hit because the execution of orders in real-life trading can be very different from demo trading especially if you trading retail Forex. If you are just paper-trading literally with a piece of paper and recording the trades on it, then no, you would never know.
