Analysis of test results and optimisation in the MetaTrader 5 strategy tester - page 3

Anatoli Kazharski:

The test time has almost dou bled.

The slowdown (4 months) was not reproducible.

Where did the tick streams from the other characters come from in this test?

Well, there really is that. It looks like a bug.

fxsaber:

No playback of the slowdown (4 months).

This, however, does indeed exist. It looks like a bug.

Try to take a longer period for the test. Although, if the "trickle down" of character streams from previous tests is reproduced, then the reason for the slowdown is clear.

Slava:

We will see what can be done.

You are describing too exotic cases.

In any case, if the environment has not been changed, and only the input parameters of the EA are changed, all caches - history and ticks - will remain intact and at the ready.

Changing the list of characters to be tested is already considered as a change of environment. But now, unfortunately, there is only possibility to specify symbols to be tested through a file or an input parameter.

You could put the selection of characters to be tested in the tester settings. Then it would "see" that the environment has changed. Consider this option as part of tester development.

Let's compare the results of the same expert that was presented in the first post of the thread with the new scheme thatfxsaber suggested in post #18

Results in the old version:

//---

Results in the new version:

//---

The number of deals shows that there are no violations affecting the trading logic in the new scheme. The duration of the tests has decreased significantly.
