Trading style: around the clock scalper with a very tight stop loss (4 pips for the L version, 2 pips for the S version) and with a much larger take profit target (13 pips for the L, 11 pips for the S). Naturally, the losing trades are predominant but overall it still makes good headway.

Timeframe: H1
Price: $127

Trading style: a scalper with a trailing stop that trades breakouts, taking into consideration the current support and resistance; for EURUSD the maximum SL is 40 pips from the entry price and the profits can even exceed 100 pips on occasion, while on GBPUSD the strategy is a bit different, allowing for a SL as high as 200 pips but also with a higher average profitable trade.

Trading style: Ray Scalper is a strategy that uses an algorithm named "backward ray tracing" for determining its entry and take profit target; the stop loss, take profit and trailing stop are dynamically calculated based on the average true range. Even though its name says "scalper", the average profitable trade is in excess of 30 pips and the average trade length exceeds 10 hours.

Trading style: based on volatility, it opens multiple trades with a fixed lot size attempting to capture trend movements; this EA is the successor of Forex Growth Bot and the trading style is similar with the exception that Forex Invest Bot might open a lot more trades (I've seen it exceed 20 concurrent trades) and it uses an improved entry & exit system.

Trading style: grid limited to 3 trades, with the entries at 60 pips distance from each other, operating in an average-down style; it has a seemingly dynamic TP (10 pips overall in grid mode) and it also has an internal SL.
