strategy tester works with the history and the base on incomplete quotations, the spread in the strategy tester is fixed (Exception only for MT4).
Therefore, in the strategy tester, there are no situations of sharp movements of quotations. There are no sharp price leaps that a broker assumes when trading on the market. Because the advisor is working on the spread and the sharp jumps in quotes and prices, it can not be checked on the strategy tester. Please download the demo version of the Expert Advisor and test it on the demo account, at least.
Can I test the EA in the strategy tester?If you do not want to believe my experience, then you can test the adviser on the MT5 terminal and set a random delay and set the type: Each tick is based on Real ticks!
But you must be aware and understand that the strategy tester is the inaccurate trading results of the EA for the reasons described above!
The Expert Advisor works at the speed of quotes. This means that the Expert Advisor catches swift movements of a currency pair, usually on the news, and earns profit on such sharp movements! Strategy Tester cannot simulate real trading.
Therefore, the Strategy Tester can give opposite trading results, even if you have been trading on this account for a specific time, the strategy tester can show other results!
Tick scalper is contraindicated for Strategy Tester!
If I created a tester grail, then I would not trade on a live account! I trade and test my advisors only on real trading accounts!
I do not trust the strategy tester!
On the strategy tester, you can check the correct operation of the algorithm, but you cannot hope for 100% coincidence of the trading results between the strategy tester and the real trading account!
