Scalper for accounts with netting accounting for orders. This Expert Advisor implements a strategy of trading on the rebound from the support and
resistance levels. The Levels indicator is taken as the basic idea.
Using the settings of the internal indicator, you can set any base timeframe for calculating levels. The Expert Advisor is launched on small
timeframes, it is recommended  
PERIOD_M5.

Trading is available both with the lot size set in the settings, and with a dynamically changing lot, depending on the settings of the
cost engineering/money management (MM) parameters.):

The Expert Advisor has several built-in filters, two of which can be changed by the user.

The filter by trading time stops working in less stable-night time (in the basic settings, it is set to UTC 3);

The volatility filter allows operation at values higher than those set in the settings. For the free version, there is a limit
on trading with volatility above 250 pp. on the base timeframe.

The full
version of the Levels Scalper Expert Advisor without restrictions is here.

The Expert Advisor can be used on any currency pairs; to confirm the possible effectiveness, it is advisable to test and
confirm or adjust the settings of the input parameters. When testing, you need to get a history quality
of at least 100% (highlighted in red in the screenshots), otherwise the result will be incorrect, just like for any other scalper.

Input parameters:

–    
Lot 0.01-setting a fixed lot size at the discretion of the trader. If the lot size is set to more than 0.0, then the settings are MM
( 
Leverage and  
Risk ) is disabled.

 –    
Leverage 1: 500-the leverage is set based on the leverage represented by your broker. You can also set a
lower leverage to reduce risks. Works when  
Lot = 0.0.

 –   
Risk 70% – the risk value is set based on the test results, taking into account your margin
expectations.    
But remember! the higher the risk, the greater the probability of losing the deposit. For example, in this case, the risk of 70% (with a leverage of 1:500) is the
limit of holding the deposit, and the risk of 100% leads to the loss of the deposit. With a leverage of 1: 50, a greater risk is allowed (more than 100%). Works when
  
Lot = 0.0.

 –   
Account base currency – the base currency of the account is set according to the deposit currency. In this version, USD (you can
choose if the base currency of the account is EUR) and RUB are available.

–     
TimeFrame PERIOD_H4 – the base timeframe for calculating levels. The base timeframe must be older than the timeframe on which
the chart is open. Usually, it is suitable for displaying a graph  
PERIOD_M5.

–      
Volatility Level 630 – the minimum amount of volatility on the base timeframe at which trading is allowed.
It can take any positive values, the operating range is 50-800 pp. At lower values, a lot of small trades are opened and the
result is leveled by the spread and commission. A significant effect can be achieved when  
Volatility Level > 100.
