Hi Apprentice,
I Check again this strategy today Saturday April 9th with the SDK… Always the same issue, it doesn’t take positions.
I take a look at the code of the strategy for the triggers to enter an order BUY or SELL, the lines 283 and 291 are : 283 if Indicator.DATA:colorI(period) == core.rgb(0, 255, 0) and Indicator.DATA:colorI(period-1) ~= core.rgb(0, 255, 0) then ….
291 elseif Indicator.DATA:colorI(period) == core.rgb(255, 0, 0) and Indicator.DATA:colorI(period-1) ~= core.rgb(255, 0, 0) then …
Also, I look at the indicator, the method “colorI” is not existing in the code
I try to replace “colorI” by the streams ZL and DN which are declared in the indicator, but the SDK sends an error when the test is launched
ERROR “ attempt to call method ‘ZL’ (a nil value)” in file “C:/Gehtsoft/IndicoreSDK3.1.0/strategies/Custom/Zero Lag Indicator Strategy.lua” at line #283
can you help ?
Thanks for replying

Following my last posts about the non behavior of this strategy with SDK 3.1.0
I’ve searched where the error could be intervene and I check all indicators and strategy with SDK 2.3.1
When Checking the strategy, I got at each tick from Quote Manager this error :
…K2/strategies/Custom/Zero Lag Indicator Strategy.lua:278: …icoreSDK2/indicators/standard/ZERO LAG INDICATOR.lua:72: C:/Gehtsoft/IndicoreSDK2/indicators/standard/ema.lua:67: attempt to perform arithmetic on local ‘sourcePeriod’ (a nil value)
The codes of different lines in the error messages are :
Zero Lag Indicator Strategy line 278 : Indicator:update(core.UpdateLast);
ZERO LAG INDICATOR line 72 : EMAI:update(mode); //(1st line of the function update)
ema.lua : line 67 : internal[period] = (1 - k) * value + k * sourcePeriod;
When I check the ema indicator with the SDK 2.3.1 debbuger : no errors
When I check the ZERO LAG INDICATOR with the SDK 2.3.1 debbuger : an error appears (in Output tab):
The object does not exist (C:\Gehtsoft\IndicoreSDK2\indicators\standard\standard)
The indicators are located in the folder C:\Gehtsoft\IndicoreSDK2\indicators\standard
The strategiesare located in the folder C:\Gehtsoft\IndicoreSDK2\strategies\custom
those folders are well indicated in the “Preferences” of the luaeditor of SDK 2.3.1
Thanks for help

I can not vouch for modified indicator version.
Indicator.DATA:colorI(period) will return indicator stream color, for a given period.
ZERO LAG INDICATOR line 72 : EMAI:update(mode); //(1st line of the function update)
On line 72 you’ll find
Code: Select all
local err = source[period] - ZL[period - 1]
Do you use the right Indicator version?

Hi Apprentice,
Yes of course, the versions come from forum

hi, I’ve downloaded the version here
[url]viewtopic.php?f=17&t=2511#p5534[/url]
It seems OK now, I will try to check with SDK 3.1.0 and send feedback
