How to use the ChangeParameters() in the strategy

Postby guangho » Fri Dec 09, 2016 10:23 am

Hi everyboby...
I have one strategy, the name is "EMAIL.lua".Sometimes, it will automatically suspend the operation because of the interruption of the network.So I want to check and restart it by "A1.lua"....

But I have tried many times not to be successful, how should I write this strategy?
Thank you for your help me...

Code: Select all
---------------------------------------------------------------------------------
"EMAIL.lua":

function Init()
strategy:name("EMAIL");
strategy.parameters:addString("TF","time","","m30");
strategy.parameters:setFlag("TF",core.FLAG_PERIODS);
strategy.parameters:addString("Email","Email","","abc@gmail.com");
end

local TF;
local Email;
local Source;
local first;

function Prepare()
TF=instance.parameters.TF;
Email=instance.parameters.Email;
local name=""..TF.."Email,"..instance.bid:instrument();
instance:name(name);
Source=ExtSubscribe(1,nil,TF,true,"bar");
first=Source:first();
end

function ExtUpdate(id,source,period)
if period>=first then terminal:alertEmail(Email,"Email",""..instance.bid:instrument()..",bid"..instance.bid[NOW]) end
end

dofile(core.app_path().."\\strategies\\standard\\include\\helper.lua");

----------------------------------------------------------------------------------------

"A1.lua":

function Init()
strategy:name("Demonstration of the pausing strategy/alert");
strategy:description("");
strategy.parameters:addBoolean("Active", "Active", "", true);
end

local active = false;

function Prepare(onlyName)
instance:name(CheckParameters(instance.parameters));
if onlyName then return end
ChangeParameters();
end

function CheckParameters(params)
local mode;
if params.Active then mode = "Active" else mode = "Paused" end
return "EMAIL" .. "(" .. mode .. ")";
end

function ChangeParameters()
active = instance.parameters.Active;
end

function Update()
if not active then return end
end
