EA automated trading using Martingale and Grid strategy If you have found this it is likely that you already understood what is this trading strategy. Basically the script will decide on a direction using previous high and low with relative strength indicator (RSI). Once the direction is decided, the script will make a order (either buy or sell) at the designated lots. Every time a trade is made, the script will calculate the take profit price point for all open orders to ensure profitability. If the first order hit take profit, the trade ends and the script will restart. Otherwise, once the live price hit the previous price + pip step, it will open a new trade provided if it is not within the same time bar.

Bollinger Bands were born in 1983 The key to Bollinger Bands is volatility BandWidth is most useful for identifying the Squeeze (Upper BB - lower BB)/middle BB Use the Squeeze as a setup Bollinger Bands can help clarify Ws Tops are more complex than bottoms; hence they are harder to diagnose 3 pushes to a high is a very common formation Low volatility begets high volatility and vice versa Avoid collinearity Volume indicator formulas One balance volume = volume + the sign of the change Volume-price trend = volume + percentage change Negative ...
