Specification

i need a robot based on this indicator with the possibility to add hours and choose the days to trade, also when the new signal appears close the last position and open the new one, there must be only one trade per time, leave the indicator attached to the symbol.

code:

//|  Parameters of drawing the bearish indicator |
//+----------------------------------------------+
//---- drawing the indicator 1 as a symbol
#property indicator_type1   DRAW_ARROW
//---- Magenta color is used as the color of the bearish indicator line
#property indicator_color1  Magenta
//---- thickness of line of the indicator 1 is equal to 4
#property indicator_width1  4
//---- displaying of the bearish label of the indicator
#property indicator_label1  "Brain1Sell"
//+----------------------------------------------+
//|  Parameters of drawing the bullish indicator |
