Akonahle som sa prihlasil, tak mi pisalo, ze mam equity a margin 0 ale cislo demouctu sedelo. Pocuj myslim si, ze ty bi si sa v tom mohol vyznat-nevies ako by som naprogramovat expert advisora tak, aby sa pri odrazeni od fibbonaciho ustupu otvorila pozicia? Logaritmus zvladam, ale neviem co mam urobit, aby sa mi retreacement posuval ked cena dosiahne nove minima a teda aj pozicia by sa otvorila v takomto pripade na inej hladine. Vies mi nieco k tomu povedat?

How to determine if an indicator is suitable for Expert Advisors

Most Expert Advisors use one or more indicators. MetaTrader platform delivers a set of build‑in indicators and additionally a possibility to write own indicators (Custom Indicators). Unfortunately, a lot of indicators that can be found in the Internet can't be used by Expert Advisors, because for example they are badly implemented or they only draw objects and can't be used in a standard way. The other common reason for disqualifying an indicator is the usage of data taken from the future in calculations (not only current and past candles). For example to calculate the value of 5‑period simple moving average for a bar at 2008.01.01 12:00 on a H1 chart, we need bars from 8:00, 9:00, 10:00, 11:00 and 12:00. Now, imagine that certain indicator uses bars from 8:00 to 14:00 to display value at 2008.01.01 12:00. So it uses 2 bars taken from the future. How is it possible? It is possible only on the basis of historical data. In live trading these 2 future bars of course won't be available. That's why this indicator will look different on a historical data and after some time in live trading. Sometimes such indicators change values not only for the most recent bar. We call such behaviour "redrawing". Generally, such indicators aren't suitable for an Expert Advisors. In rare cases, some of indicators that redraw can be used, but it must be fully conscious. A good example of an indicator, that redraws but can be used (but very consciously) in Expert Advisors, is ZigZag, which is provided with MetaTrader terminal.

Below there are 3 steps which will help you test indicators and check if they are suitable for an Expert Advisors.

Open Fibo Order

This is simple script which opens positions according to a Fibonacci Retracement object. OpenFiboOrder script has just one input variable — number of lots. The script searches for the latest Fibonacci Retracement object. Order open level is set to 1 pip over 100 fibonacci level for buy order and 1 pip under 100 fibonacci level for sell order. SL level is fixed on 0 fibonacci level. Then the script gets the first fibonacci level over 100 and sets in this place TP, so it is possible to change TP range by modification of the Fibonacci Retracement object. OpenFiboOrder calculates proper levels taking into consideration a difference between ask and bid price (spread). Just before placing order the script checks whether SL, TP and order open levels are not too close. If any error occurs, the script displays message.

Charts before and just after execution:
