Can someone tell me what are the proper settings to get Renko bars from the getChart websocket api? I have tried both “Tick” and “MinuteBar” but in either cases I never get a callback. I know the code works since I’m able to get 1minute bar with the exact same code.

This is what I’m passing to the socket.getChart API:

{  
symbol: ‘ESM2’,  
chartDescription: {  
underlyingType: ‘Tick’,  
elementSize: 8,  
elementSizeUnit: ‘Renko’,  
withHistogram: false  
},  
timeRange: { asMuchAsElements: 100 },  
callback: [Function: callback]  
}

I also tried:  
{  
symbol: ‘ESM2’,  
chartDescription: {  
underlyingType: ‘MinuteBar’,  
elementSize: 8,  
elementSizeUnit: ‘Renko’,  
withHistogram: false  
},  
timeRange: { asMuchAsElements: 100 },  
callback: [Function: callback]  
}

neither return any values.
