I'm an algorithmic trader and quant. I have a lot of experience in building strategies, portfolios and researching markets. I pay particular attention to risk control and diversification.
My style is portfolio trading. I use more than ten diverse strategies (breakout, momentum, mean-reversion) which are combined into a portfolio. The strategies are based on three basic models and diversified using various parameters and financial instruments. Such a style allows creating portfolios with specific expected values of maximum drawdown, diversification level, profit/risk, volatility of the equity curve.
Portfolio trading has advantages over trading with only one strategy. Such trading has a lower drawdown; smaller leverage is used. A portfolio is better adapted for trading in different market regimes and has lower yield volatility.
