Check out the new article: Developing a Replay System — Market simulation (Part 18): Ticks and more ticks (II).
Obviously the current metrics are very far from the ideal time for creating a 1-minute bar. That's the first thing we are going to fix. Fixing the synchronization problem is not difficult. This may seem hard, but it's actually quite simple. We did not make the required correction in the previous article since its purpose was to explain how to transfer the tick data that was used to create the 1-minute bars on the chart into the Market Watch window.
My idea for each article is to explain and encourage people to study and deeply explore the MetaTrader 5 platform and the MQL5 language. This goes far beyond what can be seen in the codes distributed somewhere. I really want each of you to be creative and motivated to explore paths that have never been taken before rather than always doing the same thing, as if MQL5 or MetaTrader 5 brings no benefit other than what everyone does with it help.
We have a pretty simple change here. This change is intended just for creating and displaying BID and ASK values. But keep in mind that this creation is based on the value of the last deal price and will only be done when we are dealing with simulated values. By running this code, we will get an internal representation of the graph generated by the RANDOM WALK system, just like we did when we used EXCEL to do it. When, in the article "Developing a Replay System — Market simulation (Part 15): Birth of the SIMULATOR (V) - RANDOM WALK", I mentioned that there were other ways to do the same visualization, I was referring to this model. But then it was not the time to say how to do it. It's time now.
If these BID and ASK values are not created, we will only be able to display the value based on the last simulated price. This may be enough for you, but some people really like to look at the BID and ASK value. However, using data in this way is not entirely appropriate. The fact that operations are carried out precisely within the BID and ASK, without actually touching them, indicates that direct operations are performed in the market. So, deals are performed without the order book. In this case, the price should not move, although it does, as we will see in the simulator. Therefore, we only need to fix the part that is highlighted in green. This is done so that the movement is at least consistent with what one would actually expect.
