As forex trader you should be familiar with the term “market gap”. Stock traders know this term from the first day they start trading. Gaps are areas on a chart where the price of a stock (or another financial instrument) moves sharply up or down, with little or no trading in between. As a result, the asset’s chart shows a gap in the normal price pattern.

Therefore its always recommended to ask you EA developer to create a Gap filter.
