Laguerre scalper - Advisor on the Laguerre indicator

Hello dear forex traders. We are often asked how the theoretical calculations and indicators posted on the site are applicable to real trading. There are also questions, how relevant are informational materials for a volatile forex market, how much can indicator systems be “converted” into profitable robots? Well of course you can! With the right approach, you can make a profitable adviser from the materials of the site. This is confirmed, among other things, by the adviser Laguerre scalper, which uses the Lagerra indicator, considered in an article by our colleague SilentSpec, which then realized the potential of this indicator in the adviser. In this review, we will test and analyze this profitable, but free advisor.

Attention! In this adviser, the settings significantly affect the trading results; use the recommended set-file (see the archive at the end of this article).

Advisor Strategy

The EA refers to trending robots that trade with increased volatility. The trend is determined using the Laguerre indicator, then the input is filtered by the LaguerreMA and Williams Percent Range (WPR) indicators. At the placed order, stop loss and take profit are set, which are trailed with a certain step, and can be closed by the signal of the Laguerre indicator. The adviser can skip entries on the FFcal news indicator, but it can also be “not afraid” of them. The EA applies topping when moving an open order to stop loss. If an open order goes into drawdown, then a second, additional order is placed, but reduced lot, and with the same stop loss and take profit as the first. This little trick can increase profitability.

Martingale in this advisor not applicable.
