Explain what behaviour of the strategy you need.

Fist enter = the prise cross EMA20 and close. + new 1 bar.
                   Цена пересекла и закрылась над скользящей средней при этом сформировался еще 1 бар
Не обязательно что бы это была бычья свеча как показано на рисунке - там важно, что бы цена закрытия не опустилась ниже EMA - покупка по цене закрытия свечи

second enter = the EMA 20 and SMA 50 cross

there are mistakes, can you help me? I have a rihgt parameters, but I do not how?

What are the mistakes? Explain what behaviour of the strategy you need.

From what I see, the strategy will not close at the upper band of Envelopes as it's shown on the chart, but will close at the first bar that closes above the lower band.

[Closing Logic Condition]
Envelopes
     The bar closes above the Lower Band

If you want to close at the upper band, you have to use:
