For example, let's look at the MACD signals. A total of 5 buy signals and 5 sell signals are described (reversal, crossing with the signal line, etc.). Is there any way to get the value of these signals at any given time? I.e., form a vector of 10 elements for each bar, where each element corresponds to the signal, 1 indicates its presence, and 0 - absence? What CSignalMACD class method can be used to obtain the corresponding values?
Unfortunately, this functionality is not available as a standard feature.
Hello, help me out here. I have created a robot (my first robot). Immediately after starting it shuts down with message Expert initializing of robot (EURUSD,H1) failed. I can`t find more information about it.
Here is his code:

I don't have enough information.
Need

Questions on MQL5 Wizard:
1) //--- inputs for money
input double Money_FixLot_Percent =10.0; // Percent
input double Money_FixLot_Lots =0.1; // Fixed volume
What do these parameters mean? And how are they related?
2) Can I generate an EA which will place pending orders? If so, how?
3) What does Signal_Expiration variable mean? How do I use it?

1) //--- inputs for money

2) Can I generate an EA which will place pending orders? If so, how?
3) What does Signal_Expiration variable mean? How to use it?
1) The Money_FixLot_Percent parameter is used to set the "forced stop" level. Do not touch it.
The Money_FixLot_Lots parameter sets a fixed volume (lot), with which your Expert Advisor will enter the market.
These parameters are not interrelated in any way.
2) Any Expert Advisor generated by the Wizard can trade pending orders. For this purpose the ..._PriceLevel parameter is used. Depending on the value of this parameter, the Expert Advisor will behave as follows:
0 - market entry will be at the current price;
>0 - market entry will be done using pending limit orders (better than the current price by the value of this parameter);
<0 - market entry will be made using pending Stop orders (worse than the current price by the parameter's value);
3) The Signal_Expiration parameter sets the lifetime of a pending order (in bars of current timeframe).
If I generate an EA in MQL5 Wizard, how many orders can such an EA open simultaneously? How is this regulated?
If I generate an EA in MQL5 Wizard, how many orders can such an EA open simultaneously? How is this controlled?
1 order. It is not regulated.
The Wizard is designed for strategy testing. If you want more, you need to "file" (write by hand).
2) Any EA generated by the Wizard can trade pending orders. For this purpose the ..._PriceLevel parameter is used. Depending on the value of this parameter, the Expert Advisor will behave as follows:
0 - market entry will be at the current price;
>0 - market entry will be done using pending limit orders (better than the current price by the value of this parameter);
<0 - market entry will be made using pending stop orders (worse than the current price by the parameter's value);
In what units is the PriceLevel parameter measured? In points? I.e., if I want to place a pending stop order 20 pips higher than the current price,
should I set this parameter PriceLevel =-0.0020 ?
