FXCodeBase.COM: Forex Chart Indicators and Development

Hi,

Am trying to learn Lua. Have a few doubts if you could help me out with this strategy:

Is it possible to set the alerts based on ticks [or a smaller time-frame] instead of candles like requested above in lua?
Also, when I back test any strategy, does the backtester also take into account transaction costs in the FXCM platform?


Any guidance would be very helpful.

Thanks,
Abhishek

Hi Abhishekc,

Is it possible to set the alerts based on ticks [or a smaller time-frame] instead of candles like requested above in lua?

Your code should contain a snip like this: 
ExtSubscribe(1, nil, instance.parameters.Period, instance.parameters.Type == "Bid", "bar");

The strategy will work with the specified periodicity. For ticks should contain the following code snip: ExtSubscribe(1, nil, "t1", instance.parameters.Type == "Bid", "tick").

Also, when I back test any strategy, does the backtester also take into account transaction costs in the FXCM platform?

Unfortunately, currently there is no such a function.
It is added to the development wish-list.

Thanks. I am trying to write a script for trading at tick data while the channels are being formed based on bar data ...Could you please have a look and advise if this looks ok? I am basically subscribing to both tick and bar data, forming the channels on bar data while the comparison for trade entry and exit is being done on tick data.

Thanks,Abhishek

Guys, I am very new to Lua ... this is not taking any trades FYI

Thanks,
Abhishek

Set "Allow Strategy to trade" to Yes

I meant it is not showing any alerts - the version which I uploaded... If someone could help out - would be great!

PolynomialRegression_Strategy2.lua is not opening any positions even the sound alert is not. i set allow to trade to yes with all original settings. could you review and fix it please ?? with my appreciation in advance.

I'm having the same issue. Strategy is set to allow trading but no trades are being executed. Everything else seems to be in order.

easytrading, Any luck finding a solution?

Apprentice, do you have a potential cause/fix for this? Any advice where we might look?

I'm using FXCM Trading Station

Hi Apprentice,

I'm getting the error below when optimizing both Polynomial Regression strategies.

Error occurred while backtest run. Description: attempt to index upvalue 'PR' (a nil value) 10/03/2016 23:17:24

Please re-download.

For this strategy please installed polynomial regression indicator. (viewtopic.php?f=17&t=3715).

Strategy was revised and updated.
