I have a little problem with strategy programm

[davidpc85]

Hello.

I have created a very simple bot to test and learn. But I have a little problem. The only thing the bot does is print data from some indicators.

For example, I select a period of three days and I have a real graph with some indicators and some parameters given by me. These same parameters I have used to initialize indicators in MQL5.

When carrying out the simulation, the following curiosity occurs to me:

Before the day the simulation starts, the indicators have exactly the same data and the same shape as they appear on the actual chart of the index I am using, but from the time the simulation starts, the data or the shape of the indicators begins to vary significantly. I have also used a 33-day simulation to check if over time the indicators tend to match those of the real graph and if it is true that they tend to have a similar shape and data but many differences are appreciated and that is what is not I have just understood. I have talked to someone and they told me to use the real ticks setting in the strategy programmer settings, but that setting was the one I had set, so the error cannot come from there.

Can someone tell me what is happening?

Thank you so much. All the best.
