474196 TL EA MT4

Hi, I need an EA to make buys off of a TL, when the TL is touched. TL will be drawn by user, and user will turn on EA, to actviate orders at the TL. TP will be fixed, and stop loss will be behind prior touch of TL. Will only take 1 order at TL, and then EA will turn off. Must open proper lot size, with user default, risk % setting. It must include a time expiration, that will have default setting. It will only take longs on upward slopping tl, and shorts on downward slopping tl.
