How can I add history to the Strategy Tester?
Why do I see different lengths of history in the Strategy Tester, depending on when I log into it? |

This article dwells on the ways of transferring an indicator code into an Expert Advisor Code and on writing Expert Advisors with no calling to custom indicators, and with the whole program code for the calculation of necessary indicator values inside the Expert Advisor. This article gives a general scheme of Expert Advisor changing and the idea of building an indicator function based on a custom indicator. The article is intended for readers, already having experience of programming in MQL4 language. |

Usualy server supplies a fixed number of bars of history data. So the longer period
of the data - the deeper history available. E.g. 1 minute bar history is about
2 weeks long, 5 munutes history is a few month long, etc.
Besides, MT doesn't load all history available automatically. You need to go through it by scrolling the chart backwards in time until all the data is downloaded.. Also the history can be truncated by MT. To keep it deep enough you need to set Tools -> Options -> Charts -> Max bars in history (as well as Max bars in chart) to a bigger value, e.g. 2147483647 (the maximum). History can be added manually via Tools -> History Center -> Import or Add. The former accepts simple text format file. |
