Bug in Multicharts Indicator SQ_SMMA

I had troubles replicating SMMA indicator, after further investigation I found an issue in the design of the indicator.
First values starting from index period to index period * 2 are 0, and there is enough data available to return correct results.

I believe there is an issue in the way you design indicators for this engine.
Because, this is not the first indicator that requires double bars than necessary to return correct results..

I think the correct way should be value None while indicator is in warming period, instead of 0.
